More renewable energy for New York

By Leave a Comment

In late October, New York announced its largest state investment in renewable energy to date that includes three offshore wind projects, and 22 land-based clean energy projects totaling more than 6 GW of power generation.

The portfolio of projects is expected to create approximately 8,300 jobs and spur $20 billion in economic investments statewide.

The projects support the state’s goal to have 70% of its electricity come from renewable sources by 2030 and to have 9 GW of offshore wind operating by 2035.  The announcement represents the first set of actions taken by the State as part of New York’s 10-Point Action Plan.

The three offshore wind projects include Attentive Energy One, a 1.4 GW project that seeks to retire fossil fuel power generation in New York City.  Community Offshore Wind, a 1.3 GW project will make use of a new grid interconnection in downtown Brooklyn.  Excelsior Wind, another 1.3 GW project, will provide robust energy deliverability to Long Island. 

Apart from the offshore wind projects, there will be 14 new solar projects, six wind upgrading projects, one new wind project, and one return-to-service hydroelectric project.

The average bill impact for customers over the life of the land-based projects is estimated to be approximately 0.31%, or about 32 cents a month for the average customer.  The bill impact for customers utilizing the offshore wind projects is estimated to be about 2.7%, or $2.93 per month.

A Groundwater Crisis | Earth Wise

By Leave a Comment

The majority of U.S. drinking water systems rely on groundwater, as do America’s farms.  Even though groundwater is a crucial resource for the country, there is no central oversight or even monitoring of its status across the country.  The health of the country’s aquifers is difficult to gauge.

The New York Times spent months amassing data from 80,000 wells across the country by reaching out to federal, state, and local agencies nationwide.

The survey found that 45% of the wells examined showed a statistically significant decline in water levels since 1980.  Forty percent of the sites reached record-low water levels over the past 10 years, with last year the worst yet.

Over pumping is the biggest problem.  State regulations tend to be weak and there is no federal oversight.  The warming climate reduces snowpack, which means less water in rivers, increasing the need to tap into groundwater.  Warmer weather means thirstier plants, increasing the demand for water.

It is a nationwide problem, not just one in the drought-ridden West.  Arkansas, which produces half of the country’s rice, is pumping groundwater twice as fast as nature can replace it.  Three-quarters of Maryland’s wells have seen substantial drops in water levels.

As groundwater is pumped out, the empty space can collapse under the weight of the rock and soil above it, permanently diminishing the capacity for future groundwater storage.

There are likely to be parts of the U.S. that run out of drinking water and groundwater depletion threatens America’s status as an agricultural superpower. Objectively, the status of American groundwater is a crisis that threatens the long-term survival of communities and industries that depend on it.

Two Lost Lakes Return To California | Earth Wise

By Leave a Comment

The recent siege of powerful storms in California driven by a series of atmospheric rivers has had a significant effect on the severe drought that has plagued most of the state for many years.  Many of the state’s reservoirs are at the highest level they have been for decades.   The snowpack in the Sierras is well over 200% of its historical average.  Many parts of the state are no longer considered to be in drought conditions, and, in fact, flooding has been a serious problem in some areas.  This flooding has had some surprising results.

Two California lakes that drained a century ago have reappeared as a result of floodwaters from the recent storms.

Tulare Lake, in California’s Central Valley used to be fed by rain and snowmelt from the Sierras.  A system of dams and canals constructed in the early 20th century to support regional agriculture diverted water away from the lake.  It used to be the largest freshwater lake in the West but farmers ultimate planted crops in the dried lakebed.

The atmospheric river events in March inundated that farmland and once again there is water in Tulare Lake.

Owens Lake, on the eastern side of the Sierra Nevada, was long fed by mountain streams.  The 1913 construction of the Los Angeles Aqueduct redirected water to that city and desiccated the lake.   Floodwaters in March caused a partial collapse of the aqueduct and when the spill gates on the aqueduct were opened to drain the damaged areas, floodwaters poured in and partially refilled the lake.

California has suffered from drought for many years.  With its massive snowpack, as the weather warms, the state may face even more flooding.

California: Drought Or No Drought? | Earth Wise

By Leave a Comment

Just a few months ago, millions of people in California were living under challenging water conservation rules.  The past three years were the driest on record and reservoirs were depleted, landscapes dried up, and the snowpack in the Sierras at very low levels.

But in recent months, a dozen atmospheric river storms have brought huge amounts of rain and snow to the state.  Twelve out of 17 major reservoirs in the state have been replenished, the snowpack is over 240% of normal, and brown hills are blooming once again.

So, is the California drought over?  According to the experts, the answer is:  sort of.

The record snowpack and heavy rains have erased the most severe aspects of the drought in many parts of the state.  Only 9% of the state is now experiencing “severe” or “exceptional” drought, down from 55% last fall.

But the changes are basically all at the surface.  Groundwater in the state is still extremely low and the state’s cities and farms are still using more of it than is appropriate.  The state has been unwisely overusing its groundwater aquifers because of the drought and this one year of heavy rains cannot replenish levels that have been dropping for years.

California has been rolling back many of the most severe drought restrictions that had been imposed but has not entirely lifted the drought emergency status.  Meanwhile, the massive snowpack in the mountains will begin to melt as the weather warms and, in many areas, Californians will face flooding.  Water is a complicated business in California.

California Storms And The Megadrought | Earth Wise

By Leave a Comment

California experienced its wettest 10-day period in 25 years as a result of a series of storms driven by atmospheric rivers in January.  The Rocky Mountains got buried in snow from the same weather pattern.   For the drought-stricken West, the storms were good news.  But they are not the cure for what’s been ailing the region.

In California, the snowpack in the Sierra Nevada mountains has been greatly enhanced, containing twice as much snow as is considered average for this time of year.  Without a doubt, it will reduce the impact of the drought that has plagued the state for 23 years.  But one big storm or even a series of them is not enough to undo years of minimal precipitation and rising temperatures.  Many of the states’ largest reservoirs remain well below historical averages despite the record-breaking rain.  It would take several wet years to really allow the state to recover from the drought.

The snowfall in the Rockies is crucial because it is the source of more than two-thirds of the water in the Colorado River.  The Colorado River is the water lifeline for 40 million people from Wyoming to Mexico.

The ongoing shrinking of the Colorado River is a crisis that has created massive problems for the multibillion-dollar agriculture industry and for many large cities, including Denver, Phoenix, Salt Lake City, Las Vegas, and Los Angeles.  Two of the nation’s largest reservoirs – Lake Mead and Lake Powell – are filled by the Colorado River.  The historic low levels of these reservoirs have threatened the functioning of hydropower facilities that provide electricity to millions of people.

The January storms were good news for the West, but its problems are not over.

The Race For EV Batteries | Earth Wise

By Leave a Comment

Lithium-ion batteries have been the power source for electric vehicles since 2008, when the Tesla Roadster was introduced.  They took over for nickel-metal hydride batteries that powered most hybrid electric cars such as the Prius.  Lithium-ion batteries store much more energy for a battery of a given weight, which leads to greater driving range.

But lithium-ion is not an ideal solution.  The batteries depend on critical materials that are obtained by hacking into mountains, utilizing scarce desert groundwater, and in some cases, making use of child labor. Many materials depend on countries with whom economic ties have complicated geopolitical consequences.

State and federal mandates and incentives are pushing auto companies to prioritize electric vehicles in their future plans.  The Inflation Reduction Act in particular provides credits and other incentives for both consumers and manufacturers to electrify. So, sources for EV batteries are a key issue.

The Department of Energy is funding 20 different companies with $2.8 billion to bolster the production and processing of critical minerals in the U.S.  The goal is to bring the electric vehicle supply chain onshore to the greatest extent possible.  Some of the work involves redesigning lithium-ion batteries to reduce or eliminate problematic materials such as cobalt.  Other efforts seek to find domestic sources of critical materials such as lithium without causing serious environmental problems.

Given all this, it is no surprise that academic and industrial researchers are also exploring a wide variety of alternative battery technologies. 

The future of transportation is electrification and the race for EV batteries is on.

California Offshore Wind | Earth Wise

By Leave a Comment

California has tremendous potential offshore wind resources.  The state set a preliminary target of 15 GW of offshore wind by 2045 earlier this year and may increase that number to 25 GW.  But installing offshore wind on the West Coast is much more challenging than it is on the East Coast.  The reason is that the ocean floor drops off rapidly on the Pacific Coast and it is simply not practical to attach wind turbines to the sea bottom.  Instead, floating turbine technology will be required.  That is more complicated and more expensive.

Despite the challenges, offshore wind in California is moving forward.  The federal Bureau of Ocean Energy Management announced that the auction for rights to develop waters off central and northern California will be held on December 6.  This will be the first wind auction ever along the U.S. Pacific Coast.

The auction will include three lease areas in the Morro Bay Wind Energy Area and two proposed areas in the Humboldt Wind Energy Area.  Combined, the two areas cover over 370,000 acres and could potentially host over 4.5 GW of wind generating capacity.  The projects developed in these areas are likely to become the first floating offshore wind projects in operation in the U.S.

Apart from the challenges of building floating wind installations, there will be the issue of the electric grid in the proposed regions being able to support the added generation from the wind farms.  Substantial grid upgrades will be needed to accommodate all the power coming from the offshore facilities.  In addition, California offshore wind projects will need to jump-start new supply chains in the U.S.

A Bad Year For California Rice | Earth Wise

By Leave a Comment

Rice production is the third largest cereal crop in the United States after corn and wheat.  Four regions in the country produce almost the entire U.S. rice crop:  the Arkansas Grand Prairie, the Mississippi Delta, the Gulf Coast, and the Sacramento Valley in California.  Arkansas is the largest producer of rice in the country by far, but California ranks second.

A combination of drought and water shortages in the Sacramento Valley has taken a major toll on the California rice crop.  This year, rice growers have only planted half as much grain as usual.  The changes in rice plantings in California are so substantial that they are easily visible from space.

In Colusa and Glenn counties, rice acreage this year dropped by 84 and 75 percent respectively, compared to 2021.  Farther to the east, in Butte Country, rice acreage was down by 17%.  The change was smaller there because farmers in that county had more groundwater to tap into.

According to the USDA, the California rice crop will be reduced by 38% this year, making it the smallest rice crop in the state since 1977.  California mostly grows short- and medium-grained rice, which is used in dishes like sushi, paella, and risotto.  Arkansas and other states produce most of the long-grain rice such as basmati and jasmine rice.

In late September, there was a burst of rain, which offered some short-term relief for farmers.  However, it will take much more wet weather to ease the ongoing drought conditions.  As of the end of September, over 40% of California remained in extreme drought and 17% was in exceptional drought.

Beavers As Climate Change Fighters | Earth Wise

By Leave a Comment

California is fighting the effects of climate change on multiple fronts.  The state has been grappling with relentless drought, record heat waves, and persistent wildfires.  The California Department of Fish and Wildlife is enlisting the help of beavers in its battle against climate change.

The state has created a beaver restoration unit charged with developing methods for nature-based restoration solutions involving beavers as well as artificial beaver dams. The agency plans to spend at least $3 million over the next two years to oversee a restoration program for the North American beaver.

A 2020 study showed that beaver-dammed corridors were relatively unharmed by wildfires compared with other areas that lacked beaver damming.  The study highlighted the differences between two adjacent corridors – one without a beaver population with a landscape scarred by a recent wildfire and another with beavers that remained a lush wetland after a fire.   The differences in burn severity, air temperature, humidity, and soil moisture between the beaver complex and the adjacent landscape were huge. 

From the 1920s through the 1950s, California actively exported beavers to other parts of the state and country so they could build dams in eroded areas where beaver dams could help evenly distribute water.  Now, the state wants to reintroduce beavers into watersheds where they once flourished.

The Department of Fish and Wildlife’s proposal to the California Legislature called beavers an important keystone species that can be used to combat climate change.   The state has spent enormous amounts of money on wildfire measures with minimal results.  Now they are going to see if beavers can make a difference.

California Climate Legislation | Earth Wise

By Leave a Comment

At the end of its summer session, California’s state legislature passed five climate-related bills including ones that it had been unable to pass in previous sessions.  Taking all of these actions puts California in the position of blazing a trail for the country and the rest of world in taking aggressive action on climate issues.

One bill confirmed California’s goal of reaching net-zero emissions by 2045.  Another bill added interim-term targets to go along with the state’s goal of 100% renewable electricity by 2045.  It sets a target of 90% by 2030 and 95% by 2040.  That bill mandates that California state agencies use 100% clean energy by 2035, which is a decade earlier than the previous requirement.

A third bill requires the California Air Resources Board to determine steps and regulations for carbon-capture and storage projects at pollution hotspots like oil refineries.

A fourth bill requires the state to set goals for removing carbon dioxide from the atmosphere through natural means such as tree planting.

The California state budget includes a record-breaking $54 billion to be spent on climate programs over the next five years, including $6.1 billion toward electric vehicles, $14.8 billion towards public transit projects, more than $8 billion for electric grid stabilization, $2.7 billion towards preventing wildfires, and $2.8 billion towards managing drought.

California has been dealing with ongoing drought and numerous wildfires and is highly motivated to take decisive action in dealing with the climate crisis.  California’s environmental initiatives often result in comparable actions taken by other states.

Weaning Off Fossil Fuels | Earth Wise            

By Leave a Comment

We recently talked about California producing 97% of its electricity from renewables on one sunny afternoon in April.  On May 8th, the state produced enough renewable electricity to meet 103% of consumer demand.  These sorts of records are likely to be increasingly commonplace in the spring when the weather is still fairly mild.

But even while renewables were producing more electricity than California needed, natural gas power plants in the state were still running.

Turning off the gas power plants is not possible.  The reason is that as the sun sets and solar farms stop producing power, California has to quickly replace the power with electricity from other sources.  Natural gas plants are massive industrial facilities that cannot be turned on and off rapidly.  Some take as many as 4 to 8 hours to switch on.  Operators back them down as far as they can go, but even when there is plenty of solar power during the day, natural gas plants are still running.

The state is rapidly building huge battery storage projects as an alternative to gas plants, but so far, they are still only a small fraction of what is needed.   Wind power is another part of the solution along with hydropower.  California imports some power from other states as well and, in fact, also exports power when there is excess.  But keeping the energy system balanced and stable is an ongoing challenge.

California is building huge amounts of solar, huge amounts of wind, and huge amounts of energy storage, which should get the state to at least 90% of the way to a clean grid.  It’s the last 5-10% that is much harder to accomplish before natural gas is no longer part of the energy system.

Community Solar In New York | Earth Wise

By Leave a Comment

New York has now installed 1 GW of community solar capacity, which is more than any other state.

Community solar is a solar energy project within a geographic area for which the benefits flow to multiple customers such as individuals, businesses, nonprofits, or other groups.  For the most part, the customers benefit from energy being generated by solar panels located at an off-site array.  Customers typically buy or lease a portion of the solar panels in the array and then receive an electric bill credit for the electricity generated by their share of the community solar system.  It is a great option for people who can’t install their own solar panels because they don’t own their home, don’t have a suitable location for various reasons, or have financial constraints.

Community solar in New York now generates enough electricity to power 209,000 homes.  Community solar installations accounted for 70% of New York’s solar additions in 2021 and the state has a pipeline of 708 more projects totaling 2.3 gigawatts.

The NY-Sun program run by NYSERDA since 2011 has directed over $200 million to low-to-moderate income households as part of its Solar Energy Equity Framework. 

Growing community solar depends strongly on policy expansion.  At this point, 19 states and D.C. have established policies and programs to support community solar adoption.  The federal government set a goal of powering 5 million American homes with community solar over the next five years.  With 30% of the country’s current community solar capacity, New York is leading the way.

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.

Quiet In The Pandemic | Earth Wise

By Leave a Comment

The early months of the Covid-19 pandemic had dramatic effects on many aspects of our daily lives.  Vehicle traffic, air pollution, and many other aspects of modern life saw reduced levels not seen in decades.  It turns out that one of the things that saw reduced levels was people’s exposure to environmental noise.

According to University of Michigan researchers, daily average sound levels dropped in half during the time that local governments made announcements about social distancing and issued stay-at-home orders in March and April as compared to noise levels measured in January and February.

The data was acquired from the Apple Hearing Study, which looked at noise exposure data from volunteer Apple Watch users in Florida, New York, California, and Texas.  The analysis included more than half a million daily noise levels measured before and during the pandemic shutdown.

The noise reduction – 3 decibels, which is a factor of two in noise level – is considered to be quite large and could have a significant effect on people’s overall health outcomes over time.

The four states studied had differing responses in terms of stay-at-home orders.  Both California and New York both had really drastic reductions in sound that happened very quickly, whereas Florida and Texas had somewhat less of a reduction.

The study demonstrated the utility of everyday use of digital devices in evaluating daily behaviors and exposures.  This sort of analysis could allow researchers to begin describing what personal sound exposures are like for Americans who live in a certain state, or are of a certain age, or who do or don’t have hearing loss.  The Apple Hearing Study is continuing and is still accepting new participants.

Global Decline In Wildlife | Earth Wise

By Leave a Comment

According to a new report released by the World Wildlife Fund, global populations of mammals, birds, amphibians, reptiles, and fish have declined by 68% in less than half a century. 

The report presents a comprehensive overview of the state of the natural world based on the tracking of almost 21,000 populations of more than 4,000 vertebrate species between 1970 and 2016. 

The report shows that the main cause of the dramatic decline in species populations on land is habitat loss and degradation, which includes deforestation driven by food production.  Additional factors include land-use change and the use and trade of wildlife.

Wildlife populations found in freshwater habitats have suffered a decline of 84%, which is the steepest decline in any biome.

Insect populations have declined rapidly in many places, but most of the information about insects comes from a small number of countries in the northern hemisphere.  There is very little information from large parts of the world, such as Africa, South America, and Asia, where land-use change and agricultural expansion are happening fast.  What happens to insects matters a lot to humanity.  Insects play central roles in the world’s ecosystems as waste processors, pollinators, predators, and prey. 

The report is clear evidence of the damage human activity is doing to the natural world.  Threats to the integrity of ecosystems endanger humans and all of nature.  This is especially apparent in the midst of a global pandemic.  It is now more important than ever to take coordinated global action to halt and reverse the loss of biodiversity and wildlife populations across the globe.

Alaska Is Getting Wetter | Earth Wise

By Leave a Comment

Siberia has been in the news for record-setting heat waves and wildfires, but it is not the only northern region experiencing unusual weather.   Alaska, apart from setting its own warm weather records, is experiencing the rainiest five years in its century-long meteorological record.

Extreme weather in the Arctic is being driven by an aspect of climate change called Arctic amplification, which leads to temperatures rising faster than the global average.  The physical basis of Arctic amplification is well understood, but its effects over time are much less predictable.

The past five years included two summers with average precipitation, one that was a little drier than usual, and two of the wettest summers on record.    Researchers have taken measurements of how far below the surface permafrost has thawed by the end of summer over a wide range of Alaskan environments.

About 85% of Alaska sits upon permafrost and the increasing rainfall over the past five years is leading to a deeper thaw of permafrost across the state.  The wettest summer on record was 2014 and permafrost didn’t freeze back to previous levels even when the next couple of summers were relatively drier.

The study demonstrated how different types of land cover govern relationships between summer rainfall and permafrost thaw.  As Alaska becomes warmer and wetter, the vegetation cover is projected to change, and the increasing occurrence of wildfires will disturb larger areas of the landscape.  These conditions are likely to lead to a feedback loop driving more and more permafrost thawing.

Fundamental changes to Alaskan ecosystems are occurring on an unprecedented timescale – not gradually over decades or lifetimes, but over mere months or years.

New Jersey And Offshore Wind | Earth Wise

By Leave a Comment

New Jersey intends to become a major hub for offshore wind in the United States.  The state recently announced a plan to build a 30-acre port along the Delaware River for assembling and deploying wind turbines, as well as an additional 25 acres for manufacturing facilities.   The new port is expected to cost as much as $400 million and create 1,500 jobs in southern New Jersey.

The port will be located on an artificial island that was built by the U.S. Army Corps of Engineers early in the 20th century.  The island is already home to three nuclear reactors.  No bridges exist between the island and the Atlantic Ocean, so turbines that are built at the staging facility could be hoisted upright and towed out to sea without obstruction.  Some components are as tall as 500 feet and when fully constructed on the ocean, the turbines selected for New Jersey’s first offshore wind project will be more than 850 feet tall.

A second phase of the program would add over 150 acres to accommodate extensive manufacturing facilities for turbine components like blades and nacelles.

Construction on the port is expected to start next year.  New Jersey has pledged to produce 7,500 megawatts of offshore wind energy by 2035 and to generate 100% of its electricity from renewables by 2050.  Apart from deploying offshore wind, New Jersey wants to have a significant piece of the supply chain for what is likely to be a growing industry along the northeast coast.  The state views offshore wind as a once-in-a-generation opportunity to not only protect the environment but also greatly expand its economy in a way that has immediate impacts and long-term growth.

More Solar And Wind Power In The U.S.

By Leave a Comment

According to the U.S. Energy Information Administration, both wind and solar power are contributing more and more to total electrical generation in the United States.  For the first 8 months of 2019, the combination of wind and solar power accounted for almost 10% of U.S. electrical generation.

Solar, including small-scale PV systems on home rooftops, grew by almost 14% compared to the first eight months of 2018 and accounted for more than 2.7% of total electrical output.  In fact, small-scale solar generation increased by 19% and provided nearly a third of all the solar power in the country. 

Wind energy in the U.S. increased by 4.4%, accounting for almost 7% of the country’s electricity.

Overall, renewable energy sources – which include biomass, geothermal, hydropower, solar, and wind – accounted for 18.49% of net domestic electrical generation during the first 8 months of 2019.  The non-hydro renewable sources actually accounted for over 11% of total electricity production and saw a year-over-year growth of 6%. 

Outside of renewables, nuclear-generated electricity declined by 0.6% and coal power dropped by almost 14%.  Much of the coal generation was replaced by natural gas, which grew by 6.5% compared to the previous year.

Renewables now accounting for nearly 20% of overall electricity generation in the US represents significant progress.  But the variations by state continue to be substantial.  For example, while Vermont gets 99% of its power from renewables, Ohio gets only 2%.

The Cost Of Rising Seas

By Leave a Comment

Coastal cities in the United States are grappling with the need for extensive infrastructure projects to protect against rising seas and worsening storms.  The cost of these projects will be enormous, and it is unclear how to pay to them.

Boston has many neighborhoods in low-lying areas, and it is estimated that $2.4 billion will be needed to protect the city from flooding.  The city abandoned plans to build a harbor barrier that would have cost $6 to $12 billion because it was economically unfeasible.

Charleston, South Caroline needs $2 billion to reduce flooding that occurs regularly during high tides.  The Houston, Texas area needs $30 billion to provide protection against a 100-year flood.  Hurricane Harvey caused $125 billion in damages in Texas in 2017.  New York City is considering a $10 billion storm surge barrier and floodgates to shield parts of the city from rising waters.

Florida faces the greatest exposure to flooding with an estimated $76 billion in costs to address some of its problems.

At the federal level, multiple agencies represent potential funding sources, but none offer the kind of money required to address the need.  This places a heavy burden on state and local governments.  Various states have passed legislation related to shoreline resiliency and flood abatement, but relatively little funding has been approved.  Some bond measures have passed, but the totals are small compared with what is needed.

Educating people about the costs of not doing anything or not doing enough soon enough is essential.  As Hurricane Katrina demonstrated, not spending a large amount of money on resilience can result in having to spend a colossal amount of money on recovery.

New York Offshore Wind

By Leave a Comment

New York has passed ambitious legislation to reduce the carbon emissions that cause climate change, but the state needs to start taking action to make those reductions possible.  One such action it has taken is an agreement that will enable the construction of two large offshore wind projects.

The projects are to be built off the coast of Long Island.  One will be 14 miles south of Jones Beach and the other 30 miles north of Montauk.  The wind farms will be built by a division of Equinor, a major Danish energy company, and a joint venture between Orsted, another Danish company, and Eversource Energy, an American firm.

The two New York wind farms are expected to be operational within the next five years and have the capacity to produce 1,700 megawatts of electricity.  That is about 20% of Governor Andrew Cuomo’s overall goal for offshore wind.

Wind farms are a major energy source in the United States, now providing about 7% of the country’s electricity.  That compares with only 2% in 2010. But nearly all American wind turbines are on land.  There is only one small offshore wind farm in the US off the coast of Rhode Island.  Things are very different in Europe.  For example, Britain expects to get 10% of its electricity from offshore wind next year, which is up from less than 1% in 2010.

Developers of offshore wind farms have struggled to gain a foothold in the US.  Some projects have foundered because of cost issues, but others have faced opposition from politicians and coastal-property owners.  But assuming the New York wind projects clear permitting and environmental hurdles, offshore wind may finally be on the move in the US.
