Harvesting Fresh Water From Ocean Air | Earth Wise

By Leave a Comment

Roughly three-quarters of the world population has access to a safely managed water source.  That means that one-in-four people do not have access to safe drinking water.  Even in the wealthy United States, persistent drought in the west is creating problems in places like Phoenix, Arizona.

Water is plentiful on Earth but more than 99% of it is unusable by humans and many other living things because it is saline, frozen, or inaccessible.  Only about 0.3% of our fresh water is found in the surface water of lakes, rivers, and swamps.

There is an almost limitless supply of fresh water in the form of water vapor above the oceans, but this source is untapped.  Researchers at the University of Illinois have been evaluating the feasibility of a hypothetical structure capable of capturing water vapor from above the ocean and condensing it into fresh water.

Existing ways to obtain fresh water like wastewater recycling, cloud seeding, and desalination have met only limited success and present various problems with regard to cost, environmental impact, and scalability.

The researchers have proposed hypothetical large offshore structures measuring 700 feet by 300 feet to capture water vapor that is continually evaporating from the ocean in subtropical regions.   Their modeling concluded that such structures could provide fresh water for large population centers in the subtropics.  Furthermore, climate projections show that the amount of water vapor over the oceans will only increase over time, providing even more fresh water supply.

This is only a theoretical study at this point, but the researchers believe it opens the door for novel infrastructure investments that could address global water scarcity.

Lab-Grown Meat Is Legal | Earth Wise

By Leave a Comment

We’ve heard more and more about laboratory meat.  Other names for it are cultured meat, cultivated meat, or test tube meat.  Whatever name ends up sticking, the idea is to take living cells from animals and grow them in a controlled laboratory environment to produce a meat product that doesn’t involve the slaughter of any animals.  Supporters say cultured meat is more efficient and environmentally friendly than traditional livestock.  Livestock agriculture is one of the largest emitters of greenhouse gases, uses vast amounts of land, and consumes much of the world’s fresh water.

Years ago, we reported on a company called Memphis Meats, which was one of a number of companies developing techniques for harvesting cells from animal tissues and using them to grow edible flesh in bioreactors.

Recently, that company – now called Upside Foods – has become the first company to receive FDA approval declaring their meat product to be safe for human consumption.  The USDA still needs to give its approval and it may be a little while longer before Upside’s first chicken products will end up in supermarkets.  There are more than 150 cultivated meat companies around the world backed by billions of dollars in investments.  The FDA is in ongoing discussions with multiple firms in the business.

Upside Foods, based in the San Francisco Bay area, is planning to market chicken, beef meatballs, and duck in the near future.  Other companies are working on seafood products.  Up until now, Singapore has been the only country in which lab-grown meat products are legally sold to consumers.  With this landmark FDA ruling, that is all about to change.

The Clean Energy Transition Is Accelerating | Earth Wise

By Leave a Comment

The world’s economies including its energy markets have been in turmoil in recent times but despite the chaotic conditions, the shift to clean energy is gaining momentum.  This year, for the first time, the world is investing more in wind and solar power than in oil and gas drilling.  Investments in renewables are expected to reach $494 billion this year, more than the $446 billion directed towards oil and gas extraction.  It is rather sobering to realize that the world is still spending nearly half a trillion dollars a year to dig up more oil and gas.

According to the International Energy Agency, there will be an estimated 340 gigawatts of new renewable power capacity installed in 2022.  This is roughly equal to the total installed power capacity of Japan, which has the world’s third-largest economy.  This year is also seeing tremendous growth in electric cars, which are projected to make up 13% of all light-duty vehicle sales across the globe.

According to analysis by Bloomberg Green, 87 countries are now getting at least 5% of their power from wind and solar.  This number is considered to be a critical tipping point at which emerging technologies become more widely adopted.  The United States reached that 5% threshold in 2011.  Last year, our country surpassed 20% solar and wind power.  If we follow trends set by pioneering countries like Denmark, Ireland, and others, wind and solar will supply at least half of our power within the next decade.

Despite the turbulence in global energy markets, the shift to clean power is ongoing.  Estimates are that global spending on renewables will double over the next 10 years.

The State Of The Birds | Earth Wise

By Leave a Comment

The U.S. Committee of the North American Bird Conservation Initiative has published the State of the Birds 2022, an assessment of bird populations in North America. The news is not good.  The report identifies 70 Tipping Point species, which are those that have lost half or more of their breeding population since 1970 and are on track to lose another half or more in the next 50 years. According to research published in Science in 2019, the United States and Canada have lost 3 billion breeding birds since 1970, which is about a quarter of the total population.

More than half of the bird species in the United States are in decline. According to the Conservation Initiative, the tipping point species in particular require proactive conservation protections to avoid becoming endangered.  Species that inhabit grasslands are declining more rapidly, while waterfowl like ducks and geese are actually increasing.  That increase is most likely a result of the investments in conservation funded by the hunting industry.

Those waterfowl gains demonstrate that when there are concerted efforts to protect and promote bird populations, positve changes can happen.  Some say that protecting birds is not a high priority given all the other crises in the world, but what is good for birds is also good for people.  For example, planting trees and other vegetation to enhance bird habitat also helps to sequester carbon, protect coastlines from storm surges, increase groundwater recharge, and reduce urban heating effects.

The loss of 3 billion birds is a major biodiversity crisis and requires action.  Bird conservation benefits wildlife, people, entire ecosystems, and our planet.

Carbon Capture Booming | Earth Wise

By Leave a Comment

For the world to reach a state of net-zero emissions, it is going to require more than the ongoing transition to renewable energy sources.  There will also need to be efforts to capture the emissions from sources that can’t easily eliminate their pollution.  These include steel mills, cement plants, and other industrial sites.  At least for the foreseeable future,  a number of essential industries have no other viable path to deep decarbonization, and carbon capture and storage projects are the only promising strategy on hand.

Companies use CCS to filter emissions from fossil fuel power plants and industrial facilities and then bury the captured carbon underground, often in deep caverns.

Over the past 12 months, the pipeline for carbon capture and storage projects has grown by 44%.  This year, firms have announced 61 new CCS projects, bringing the total number of commercial projects in the global pipeline to 196, which includes about 30 that are already in operation.  Another 11 are under construction, and 153 are in development.

When all of these projects are completed, they will have the capacity to capture a total of about 270 million tons of carbon dioxide per year.  Estimates are that there need to be 1,400 million tons locked away each year to reach zero-emissions.  So, the existing project pipeline constitutes about 20% of what is ultimately needed.

The recently passed Inflation Reduction Act boosts tax incentives for carbon capture.  Analysts believe this could multiply U.S. deployment of the technology more than 10-fold.  Globally, it is expected that CCS will continue its rapid growth as countries ramp up investments in the technology.

Green Steel | Earth Wise

By Leave a Comment

The Inflation Reduction Act provides $369 billion in investments to ramp up renewable energy generation and manufacturing of solar panels, wind turbines, energy storage, and electric vehicles. 

Every megawatt of solar power deployed requires 35 to 45 tons of steel.  Every megawatt of wind power uses 120 to 180 tons of steel.   Estimates are that it will take 1.7 billion tons of steel just to build all the wind turbines needed to reach net zero emissions by 2050.

This is a big problem because steel production accounts for roughly 10% of global carbon emissions and is one of the most carbon-intensive industries in the world.

Making steel is a complex and age-old process that hasn’t changed much over time.  Green steel is steel made with little or no carbon emissions.  There are a few ways to do it.  One is called the direct reduced iron method that uses green hydrogen instead of fossil fuel gas to produce iron and then a renewable-powered electric arc furnace to make the steel. 

Molten Oxide Electrolysis is an alternative green steel approach that doesn’t depend on having a green hydrogen infrastructure.  It uses electrolysis, powered by renewable energy, to separate the bonds of iron ore and produce liquid metal while releasing only oxygen in the process.

Green steel solutions rely on the availability of renewable energy, but the ultimate success of renewable energy will depend on the success of green steel.  The U.S. steel industry will leverage about $6 billion under the Inflation Reduction Act to make progress on it.

Banning Gas-Powered Cars | Earth Wise

By Leave a Comment

In June, the European Union voted to ban the sale of new gas- and diesel-powered vehicles starting in 2035.   The EU joined Canada, the United Kingdom, Japan, South Korea, and several other countries in imposing future gas car bans.

Here in the U.S., on August 25th, California adopted rules banning the sales of new gas-powered cars and light trucks by 2035.  New York passed a similar law last year and its ban will also cover heavy trucks by 2045.

California’s action is particularly significant because there are other states that have trigger laws that impose their own bans based on what California does.  Washington state, Massachusetts, and Virginia are in this category, although the governor of Virginia has said he plans to try to repeal the law.

An additional 12 states have policies tied to California’s and are likely to adopt their own versions of the 2035 ban.  These are Colorado, Connecticut, Delaware, Maine, Maryland, New Jersey, New Mexico, Nevada, Oregon, Pennsylvania, Rhode Island, and Vermont.

When these regulatory actions are coupled with the major investments in electric vehicles being made by virtually all automakers, the transition to electric vehicles appears to be inevitable.

As far as people who love their gas-powered cars are concerned, the new rules only apply to new car sales.  So, consumers can still buy and own used cars that run on gasoline.  If there are states that never impose bans on new gas-powered vehicles, then consumers can go to those states and buy one, assuming there are any being made at that point.   It seems likely that gas-powered cars will end up being made for hobbyists and aficionados only.

A Law To Tackle Climate Change | Earth Wise

By Leave a Comment

The Inflation Reduction Act signed into law in mid-August is the most comprehensive U.S. legislation addressing climate change ever enacted.   It contains $369 billion in funding for clean energy and electric vehicle tax breaks, domestic manufacturing of batteries and solar panels, and pollution reduction.

The legislation for the most part makes use of carrots rather than sticks to coax American consumers and industry away from reliance on fossil fuels.  Rather than establishing more carbon taxes, mandates, and penalties, the law largely makes use of tax credits to provide incentives for the use of clean energy.

The law provides a large mix of tax breaks intended to bring down the costs of solar, wind, batteries, electric cars, heat pumps, and other clean technology.  For example, consumers will get a $7,500 credit for purchasing many new electric car models and about $4,000 for buying a used vehicle.

On the stick side of the ledger, oil and gas companies that emit methane above certain threshold levels will incur fees that escalate over time.  The law also increases the cost to the oil industry for extracting fossil fuels from public lands.

The act provides $60 billion for overall environmental justice priorities, including $15 billion targeted specifically for low-income and disadvantaged communities. There are many other provisions in the law addressing multiple climate-related issues.

According to three separate analyses by economic modelers, the investments from the Inflation Reduction Act are likely to cut pollution by about 40% below 2005 levels by the year 2030.

Carbon Capture In Denmark | Earth Wise

By Leave a Comment

Denmark has pledged to reduce greenhouse gas emissions 70% by 2030 compared with 1990 levels. The country has also banned oil exploration in Danish waters and plans to phase out offshore drilling in the North Sea by 2050.

Instead of pumping oil from the North Sea, Denmark plans to capture CO2 and store it there.  To meet its climate goals, Denmark is investing $2.4 billion in a plan to capture carbon dioxide from its energy and industrial sectors and inject it into the seabed in geological formations that previously held oil and gas deposits.

The first North Sea carbon capture and storage facilities will be put into service in 2025 and will remove nearly half a million tons of emissions from the atmosphere each year.  The carbon dioxide will be captured from energy and industrial sectors such as waste incineration and cement production.

There are multiple carbon capture projects underway around the world.  Many are directed at so-called direct air capture, which is taking carbon dioxide out of the air once it is already there.  In Iceland, a project named “Orca” is extracting CO2 from the air and piping into a processing facility where it is mixed with water and diverted into a deep underground well.  Other large direct air capture plants are being built in the U.S. Southwest and in Scotland.

Whether capturing carbon from industrial operations or directly from the air ultimately makes environmental and economic sense remains to be seen.  What is driving the development of these technologies is the troubling math that reducing emissions is not happening fast enough to stave off the destructive effects of climate change that will result from global temperatures rising too much.

Major Funding For Novel Energy Storage | Earth Wise

By Leave a Comment

The accelerating adoption of wind and solar energy is driving a growing interest in energy storage technologies.  An electric grid dominated by intermittent power sources will need large-scale energy storage.  Grid-scale energy storage is expected to increase at least 10 times over the next decade and this will require nearly $300 billion in investments over that time period.

Much of the effort in energy storage has focused on battery storage.  But there are other storage technologies that are attracting attention and investment.

Energy Vault is a Swiss-based company specializing in gravity and kinetic energy-based energy storage.  Their technology uses a multi-headed crane to store energy generated by renewable sources by stacking heavy blocks made of composite material into a tower, capturing potential energy from the elevation gain of the blocks.  To produce electricity, the crane lowers the blocks to the ground, driving generators in the process.  The company has just raised $100 million in funding from investors. 

Malta, Inc. is an energy storage company based in Cambridge, Massachusetts that is developing an electro-thermal energy storage system.  Energy generated from renewable (or other) sources drives a heat pump to create thermal energy producing both hot and cold reservoirs.  The heat is then stored in molten salt while the cold is stored in a chilled liquid.  To generate electricity, the temperature difference between the two reservoirs is used to drive a heat engine.  Malta has recently raised $60 million in new funding including significant support from Chevron Energy Ventures.

Wind Power Update | Earth Wise

By Leave a Comment

The Department of Energy recently released three reports showing record growth in land-based wind energy, a growing number of offshore wind projects, and the continuing reduction in the cost of wind power.

The U.S. installed a record amount of land-based wind energy in 2020.  In total, 16,836 MW of new utility-scale land-based wind power capacity was added during the year, representing $24.6 billion in new wind power projects.  This was more added than from any other energy source and represented 42% of new U.S. energy capacity.

For the year, wind energy provided more than 10% of in-state electricity generation in 16 states.  Notably, wind provided 57% of Iowa’s electricity and more than 30% in Kansas, Oklahoma, South Dakota, and North Dakota.

As wind turbines continue to grow in size and power, they are producing more energy at lower cost.  Turbine prices have gone from $1,800/kW in 2008 to $770-850/kW now.

The pipeline for U.S. offshore wind energy projects has grown to 35,324 MW, a 24% increase over the previous year.   The Bureau of Ocean Management created five new wind energy areas in the New York Bight with a total of 9,800 MW of capacity. 

Distributed wind power, which are systems connected on the customer’s side of the power meter as opposed to those on the utility side, also saw increased growth last year. 

Wind power is a key element in the adminstration’s goal of having a decarbonized electricity sector by 2035.

A Green Light For Commercial-Scale Offshore Wind | Earth Wise

By Leave a Comment

The Biden administration has given final approval to a project it hopes will usher in a new era of wind energy in the United States.  The greenlight was announced by the Department of the Interior on May 11.

The Vineyard Wind project intends to install up to 84 huge wind turbines about 12 nautical miles off the cost of Martha’s Vineyard, Massachusetts.  In total, Vineyard Wind could generate 800 megawatts of electricity, enough to power about 400,000 homes.  The construction project will create about 3,600 jobs.  The $2.8 billion project is a joint venture of the energy firms Avangrid Renewables and Copenhagen Infrastructure Partners.

The idea of a wind farm off the Massachusetts coast was conceived 20 years ago but ran into repeated setbacks, delays, and well-funded opposition from waterfront property owners concerned about what will ultimately be the barely discernable sight of tiny blips on the distant horizon.  The Trump administration moved to cancel the permitting process for Vineyard Wind, but the Biden administration revived the project in March as part of its greater efforts to tackle climate change.

Electricity generated by Vineyard Wind will travel via cables buried six feet below the ocean floor to Cape Cod, where they will connect to a substation and feed into the New England grid.  The project is expected to begin delivering wind-powered electricity in 2023.

The Biden administration says that it intends to fast-track permits for other wind projects off the Atlantic Coast and that it will offer $3 billion in federal loan guarantees for offshore wind projects and invest in upgrades to ports across the United States to support wind turbine construction.

Solar Cell Greenhouses | Earth Wise

By Leave a Comment

A recent study at North Carolina State University has shown that it can be feasible to use see-through solar panels in greenhouses to generate electricity.  The idea is to use semi-transparent solar panels on greenhouses that allow some of the light to get in for the plants to grow while making the greenhouses energy neutral or even allowing them to generate more power than they use.

The question is how the semi-transparent solar panels might affect greenhouse crops.  To investigate this issue, researchers grew crops of red leaf lettuce from seed to full maturity under a standard set of growing conditions – temperature, water, fertilizer, and CO2 concentration – but varied the light they get. 

A control group was exposed to the full spectrum of white light while three experimental groups were exposed to light through different types of filters that absorbed the particular wavelengths of light that would be absorbed by different types of semitransparent solar cells.

The researchers paid close attention to characteristics of the lettuce that are important to growers, grocers, and consumers:  general appearance, leaf number, leaf size, and weight.  The results were that the lettuce produced using all three kinds of filtered light was essentially identical to that produced in the control group.    Further research is underway looking at how harvesting various wavelengths of light affects biological processes for lettuces, tomatoes, and other crops.

Getting growers to use solar-powered greenhouses would be very difficult if doing so would result in a loss of productivity.  But given these experimental results, it appears as though the decision will boil down to a simple economic argument about whether the investment in new greenhouse technology would be offset by energy production and its resultant savings.

New York Offshore Wind | Earth Wise

By Leave a Comment

Norwegian energy company Equinor and its strategic partner bp have been selected by New York State to build several offshore wind power installations that will be one of the largest renewable energy projects in the United States to date.  When completed, the projects will provide 1,260 megawatts of offshore wind power from Empire Wind 2 and another 1,230 megawatts from Beacon Wind 1 and these will be added to the 816-megawatt project already awarded to the companies for Empire Wind 1. 

The two phases of Empire Wind are located 15-30 miles southeast of Long Island and span 80,000 acres. Beacon Wind is located 60 miles east of Montauk Point and 20 miles south of Nantucket and covers 128,000 acres.  The overall development will provide 3.3 gigawatts of homegrown, renewable electricity to New York.

The projects will comprise up to $8.9 billion in investments including $664 million provided by the state.  As part of the award from NYSERDA, the companies will partner with the State to transform two New York ports – the South Brooklyn Marine Terminal and the Port of Albany – into large-scale offshore wind working industrial facilities that position New York to become an offshore wind industry hub.

In Albany, Equinor will join forces with wind industry companies Marmen and Welcon to help the port become America’s first offshore wind tower and transition piece manufacturing facility, where it will produce components for Equinor’s projects.

New York’s goal is to have 9 gigawatts of offshore wind capacity by 2035.  The Equinor projects will contribute more than one-third of that goal.

Drilling Rights In The Arctic National Wildlife Refuge | Earth Wise

By Leave a Comment

The battle to prevent oil and gas drilling rights from being sold in the Arctic National Wildlife Refuge in Alaska has been going on for 40 years.  The Trump administration spent nearly four years pushing to auction off those drilling rights and finally accomplished it in early January.

The ANWR was created in 1960 and is the largest intact wilderness in the U.S., covering nearly 30,000 square miles in Alaska.  It is an important breeding habitat for polar bears as well as the home of more than 200 other species including caribou, arctic foxes, golden eagles, and snowy owls.  Parts of it are also sacred ground for the indigenous Gwich’in people.

The auction carved out a 5% slice of the refuge for leases and proponents anticipated it would generate billions of dollars in revenues that would offset tax cuts in Alaska.

Of the 22 parcels of land offered, totaling 1.1 million acres, only 12 were bid on at all and the state of Alaska was the sole bidder on 9 of those.  In total, the auction raised a paltry $14 million. 

Whether the remarkable absence of interest was due to a lack of infrastructure or roads around the region, the decline of fossil fuel investments and use during the pandemic, or the anticipation that any leases would be the subject of endless legal battles by indigenous tribes and environmental activists, the net result was that the auction was basically a flop.

President Biden has stated that he is entirely against Arctic drilling, so the new administration is likely to try to repeal or interfere with any drilling leases or other industrial activity in the ANWR.

A Large Drop In U.S. Greenhouse Gas Emissions | Earth Wise

By Leave a Comment

Greenhouse gas emissions in the U.S. in 2020 are on track to be at their lowest level in nearly 30 years as a result of the COVID-19 pandemic.  U.S. emissions haven’t been this low since 1983, when the economy was not even 40% of its current size.

According to a new study by the research group BloombergNEF, U.S. emissions for the year will be 9% lower than they were in 2019, which will be the largest yearly drop on record.  The report also anticipates that whatever happens in the pandemic, 2021 emissions will be well below pre-COVID levels as well.

The pandemic has inadvertently put the U.S. back on track to meet its original commitments to the Paris Climate Agreement, despite the fact that we have pulled out the agreement.  The incoming administration plans to return the U.S. to the pact.

Overall, U.S. emissions have been trending downward since 2008, primarily as a result of the lower dependence of the power sector on coal.  The report estimates that in the absence of the pandemic, 2020 emissions would have been 1% lower than last year’s.

The dramatic drop in emissions is not really a great cause for celebration.  Achieving significant emission reductions through massive economic hardship and societal disruption does not point the way towards making progress on climate change.  The economic upturn that will undoubtedly occur when the pandemic loses its grip on the world will lead to rebounding levels of greenhouse gas emissions.  But as is the case with all major crises, the current situation does present a chance to turn this temporary downturn in emissions into a more permanent one by making appropriate investments and policy changes.

Paying To Combat Climate Change | Earth Wise

By Leave a Comment

The majority of Americans believe that climate change is happening, that human activities are largely responsible, and are actually willing to put up their own money to help fight it.   Unfortunately, these views diverge sharply along party lines and, as in many other areas these days, the will of the overall majority has little influence on policy.

According to Yale University research, 73% of adults think that global warming in happening and 57% think it is mostly caused by human activities.  Furthermore, only 32% believe it is due to natural forces.

A survey conducted in the U.S. in August found that more than two-thirds of Americans – actually 70% – indicated willingness to donate a percentage of their personal income to support the fight against climate change.

Breaking that down further, 28% were willing to provide less than 1% of their income, 33% were willing to contribute 1-5% of their income, 6% said they would give 6-10% of their income, and 3% said they would contribute more than 10% of their income.  On the other hand, roughly 30% indicated that they were unwilling to contribute.

The survey also looked at opinions on how the fight against climate change should be paid for.  The majority (59%) chose government incentives for both businesses and consumers.   Three other options each favored by over 40% of those surveyed were taxes, conservation programs, and business investments. 

Another finding of the survey was that 44% are dissatisfied with the job that the federal and state governments are doing to address climate change, 35% are somewhat satisfied, and only 21% are very or completely satisfied with the government’s role.

Saving Costs And Reducing Emissions From Shipping | Earth Wise

By Leave a Comment

International shipping is a large and growing source of greenhouse gas emissions.  Maritime transport produces about a billion tons of CO2 annually, accounting for about 2.5% of global greenhouse gas emissions.  The environmental impact of shipping includes air pollution, water pollution, and even acoustic pollution.  In many coastal areas, ships are responsible for more than 18% of some air pollutants.  Overall, there are more than 100,000 transport ships at sea, of which about 6,000 are large container ships.

In recent years, the shipping sector has had both internal willingness and external pressure to reduce emissions, but shipping is a tough, competitive business and it isn’t easy to stay competitive and help protect the environment.

A recent study at Abo Akademi University in Finland has found that improved ship utilization rates and investments in environmentally sustainable technologies for enhanced energy efficiency would significantly reduce carbon dioxide emissions.  Of equal importance, those same measures would contribute to lowering of freight costs.

If the same cargo volume can be shipped using less fuel, shipping companies will gain major savings in terms of fuel costs.  Digitalization can provide valuable benefits.  For example, new digital planning and booking systems would enable smarter use of routes while also diminishing traffic with half-empty vessels or even ones with no cargo aboard.  Reducing such underutilization would improve the capacity utilization rate and eliminate emissions caused by so-called ballast traffic.

Global shipping continues to grow.  It is essential that it becomes smarter and more efficient to protect the environment and improve its economics.

Stranded Coal Assets In Japan

By Leave a Comment

Japan is facing a looming financial problem as a result of heavy investments in coal technology that may quickly become stranded assets as renewable energy sources become increasingly inexpensive.

Japan is gradually adding more ambitious policies with regard to climate change including goals to reduce emissions and to have renewables become the main source of power over the next three decades.  But despite these policy efforts, Japan is still investing heavily in coal power.  Japan currently has 21 new coal projects with over 11 GW of under-construction, permitted or pre-permitted coal capacity.  But these tens of billions of dollars in assets would have to be closed prematurely in order to remain consistent with the goals of the Paris Climate Agreement.

According to a new report by the Carbon Tracker Initiative, a financial think tank, and the University of Tokyo, offshore wind power will be cheaper than coal in Japan by 2022, new solar cheaper by 2023, and onshore wind less expensive by 2025.  The price of offshore wind is already comparable to existing coal power in Japan.  Japan had a total of 55.5 GW of solar capacity last year and has the potential to reach 150 GW by 2030.

The report notes that 42% of the global coal fleet likely became unprofitable last year and this could rise to 72% by 2040.  The authors contend that building coal power today equals high-cost power and financial liabilities tomorrow.  The planned and operating coal capacity in Japan is partially protected by regulations that give coal generators an unfair advantage in the marketplace.  Ultimately, the stranded coal assets are likely to be passed down to consumers through higher power prices.

The Largest Community Solar Program

By Leave a Comment

Community solar projects allow customers to benefit from the economic and environmental attributes of solar energy when they don’t have the ability to invest in their own system for any number of reasons.

Florida Power & Light company is proposing to build the largest community solar program in the United States, pending regulatory review.  The planned installation of 1,490 MW of new solar capacity at 20 new power plants distributed across FPL’s service territory is expected to generate an estimated $249 million in net savings for all FPL customers over the long term.

In addition to becoming the largest community solar program in the country, the new program would also be the largest voluntary low-income solar offering in the country.  Low-income households are typically unable to benefit from solar energy because of not having the means to invest in the technology.  The new SolarTogether program will have more than 35 megawatts of capacity dedicated to low-income Florida families.  Solar energy is a critical tool for enabling low-income families to tap into energy savings. 

The SolarTogether program would provide direct savings in the form of bill credits, making solar an affordable option for any customer.  The Southern Alliance for Clean Energy and Vote Solar joined with FPL to help design the program to include a low-income component and request Florida Public Service Commission approval. There is broad support for the program from universities, county and city governments, and private companies.  In addition, more than 90,000 residential and small business customers have already signed up to receive more information.  The utility hopes to receive regulatory approval in time to launch during the first quarter of 2020.
