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.

Five States Stepping Up On Clean Energy | Earth Wise

By Leave a Comment

While Congress continues to face partisan gridlock on climate issues, many states have moved forward with climate action.

In 2021, five states – Illinois, Massachusetts, Oregon, North Carolina, and Rhode Island – passed laws requiring a shift to 100% carbon-free electricity or net-zero emissions.  Washington State passed a law that helps to implement its strong 2019 and 2020 climate and clean energy laws.  Washington’s new legislation establishes a carbon trading program that will help the state to meet its goals of economy-wide emission cuts and 100% carbon-free electricity.

Several other states made progress on climate and clean energy by taking targeted actions not quite as aggressive as 100% laws, but significant, nonetheless.

The five states that entered the so-called 100% club joined with the six states that had earlier passed such legislation.  Those are California, Hawaii, New Mexico, New York, Virginia, and Washington.  Both Puerto Rico and Washington D.C. are also members of the club.

The past year may well be the biggest year yet for significant clean energy legislation.  Some of the states that finally passed laws had been gearing up for it for years.  This is particularly true of Massachusetts and Illinois.

Actions by individual states are not an antidote to inaction by the federal government, but they help.  At this point, about one-third of the country’s population lives in states that have laws requiring a transition to 100% carbon-free electricity, 100% renewable electricity, or net-zero emissions. 

All of this activity began in 2015, when Hawaii passed its renewable energy law.

Florida’s Starving Manatees | Earth Wise

By Leave a Comment

Manatees, also called “sea cows”, have been the victims of farm runoff.  They have starved to death by the hundreds along Florida’s east coast because algae blooms fed by nitrogen-rich fertilizer runoff are proliferating on the ocean surface and blocking sunlight from reaching seagrass below.  Seagrass is the primary source of food for manatees in the winter.  As seagrass dies off, so do the manatees.

Over 1,000 manatees have been found dead so far this year.  It is estimated that fewer than 8,000 remain in Florida waters.  Efforts are underway to restore coastal seagrass in the region as well as clams and oysters, which filter pollutants from water.  Unless the water is cleared up, it will be difficult to regrow the seagrass.  But the current situation is that manatees are so short on food that they are eating seagrass roots, killing the plants and thwarting efforts to help seagrass recovery.

Given this dire situation, the federal governmental has approved a program of feeding manatees.  The starving animals will be fed by hand in Florida, which is a rare wildlife intervention.  Conservation agencies tend to favor leaving wild animals to their own foraging and hunting so that they don’t become dependent on human handouts.

During the trial phase of the program, wildlife experts are likely to feed the animals romaine lettuce and cabbage, which is what manatees in captivity eat.  The hope is to give the animals enough additional food for them to get through the winter.  The trial feeding will begin on private property.  It remains illegal for the public to feed manatees.

Electrifying The Federal Fleet | Earth Wise

By Leave a Comment

The federal government owns and operates about 645,000 vehicles.  Among them are about 200,000 passenger vehicles, 78,000 heavy-duty trucks, 47,000 vans, 847 ambulances, and three limousines.   About 225,000 vehicles are operated by the Postal Service.  

Each year, these vehicles are driven about 4.5 billion miles and use about 400 million gallons of gasoline, producing 3.5 million tons of greenhouse gases.

President Biden signed an executive order in January directing federal officials to devise a plan for converting the entire fleet to clean and zero-emission vehicles.  So far, the work has been slow. 

According to a new report from Atlas Public Policy, accelerating the push for electric vehicles in the federal fleet could save taxpayers billions of dollars.

Electric vehicles have lower fueling and maintenance costs as well as a smaller environmental impact.  According to the report, the government could replace 40% of its light-duty vehicles and buses not owned by the Postal Service with cheaper plug-in alternatives by 2025.  By 2030, it could replace 97% of such vehicles with EVs for a lifetime savings of more than $1 billion.  Furthermore, by 2025, it would be possible to replace nearly all mail trucks with EVs for a savings of $2.9 billion.

The federal fleet represents an opportunity to encourage transportation electrification to happen much more quickly.  Apart from the economic and environmental benefits, having an electrified federal fleet would increase public awareness of the practicality and benefits of electric vehicles.

A Solar Power Boom In Texas | Earth Wise

By Leave a Comment

Texas has been a leader in wind energy for a number of years.  In 2020, wind made up 23% of the state’s generating capacity and provided 20% of in-state generation.  But although wind capacity in Texas has grown rapidly in recent years, solar power is expected to make up the largest share of the state’s capacity additions over the next two years.

Texas plans to add 4.6 gigawatts of utility-scale solar power this year and 5.4 gigawatts in 2022.  This will give the state a total capacity of 15 gigawatts, which will nearly catch up to California, the state with the most large-scale solar power.  California already has 16 gigawatts of installed solar capacity and plans to add about two more over the next two years.

The planned capacity for Texas will provide enough power for roughly 5 million homes, taking into account the intermittency of solar energy.  Much of the new solar capacity will be in the Permian Basin in West Texas, which is a particularly sunny place.  Because solar generation is greatest in the middle of the day, when wind generation is typically lower, the transmission line infrastructure already in place for the wind power will be adequate for the new solar installations.

The boom in solar power in Texas is driven in part by the federal solar Investment Tax Credit that is available to project developers as well as by the ever-lower cost of solar technology. 

One-third of the utility-scale solar capacity planned to come online in the U.S. in the next two years will be in Texas.  Currently, utility-scale solar only makes up 4% of electrical generating capacity in Texas, but that is clearly changing.

Massachusetts And Energy Policy | Earth Wise

By Leave a Comment

The transition to a renewables-based energy future continues to accelerate, but there are still many forces that can slow it down.  Government policy has a major role to play.  At the moment, the federal government is trying to prop up the fossil fuel industry with financial incentives and rampant deregulation.  So more than ever, innovative policies at the state level are essential drivers for revolutionizing the energy system.

One state where policy is trying to make a big difference is Massachusetts, which has created the Clean Peak Energy Standard or CPS, finalized and approved in late March and now taking effect.   A clean peak standard is a regulatory tool to reduce the costs and environmental impact of periods when electricity demand is highest, and generation tends to be the most polluting.  The CPS requires electric retailers to procure a minimum percentage of their annual electricity sales from renewable generation or energy storage.  That minimum amount will increase each year.

The CPS is formulated to incentivize better utilization of clean energy technologies to supply power when energy demand is high.  The problem is that there are times when the sun is not shining and the wind isn’t blowing, but energy demand is at its highest.  The solution is to use energy storage technologies that can supply power when it is needed.  Furthermore, storage can be relied upon during times of extreme weather that cause power outages.

Massachusetts has already started using energy storage in its grid.  The small town of Sterling installed an energy storage system in 2016 that provides crucial backup power to the police station and emergency dispatch center, thereby keeping first responder operations running even during extended power outages.

Renewables Could Take Over By 2035 | Earth Wise

By Leave a Comment

A study by UC Berkeley looked at the prospects for renewable energy sources to become the primary source of energy in the United States over the next 15 years.  Even though fossil fuels continue to fill that role at present, the plummeting costs of alternative energy sources – primarily solar and wind power – are making them increasingly attractive on the competitive market.

These cost reductions have occurred much faster than what was anticipated even just a few years ago.  According to the study, it is technically and economically feasible for renewable sources to provide 90% of our electricity by 2035.

The Berkeley researchers took the available data on renewable energy and created two scenarios for the next 15 years.  The first has energy policy remaining as it is now, without ambitious policy changes that encourage the growth of renewable energy.  In that scenario, they estimated that 55% of the US energy infrastructure would come from renewables.  That amount will not produce the change needed to meet Paris Climate Agreement goals but would simply come about because of the dramatically lower costs for renewable energy.

The second scenario includes state and federal governments leading the way to finance and facilitate the energy reform needed for a greener 2035.  It also relies on the large-scale use of grid-scale batteries to store the energy collected from solar and wind installations for when it is needed.

Which scenario is more realistic will depend on several major influential factors, notably the trajectory and consequences of the COVID-19 pandemic as well as the results of the November elections.   These things will have a huge impact on the future of our energy system.

Conservation In Vermont | Earth Wise

By Leave a Comment

In recent times, Vermont and neighboring states have been losing forest land to development at a rate of almost 1,500 acres per year.  With forest fragmentation gaining ground across New England, conserving land for future generations of people, wildlife, and plants has become both increasingly important and increasingly difficult.

According to a new study published by researchers at the University of Vermont, the state has already protected a third of the highest priority targeted lands needed to protect and connect valuable wildlife habitats and corridors.  The protected lands amount to 1.3 million acres.

Most of the currently conserved lands are forested.  However, there are high-priority targeted surface water and riparian areas – ponds, rivers, shorelines, and wetlands – and not nearly enough of these have been protected.  (Many animals require zones along waterways in which to travel between the habitats they need to survive).

The state of Vermont and a number of partners have laid out a comprehensive and thoughtful vision that would ensure that Vermont remains a good place for all forms of life in the future.  The new study provides a crucial benchmark of current levels of forest protection to help prioritize future conservation actions. 

Three groups dominate in responsibility for the state’s protected lands:  the federal government, the state government, and private non-profit organizations.  (Each of these account for roughly a third of existing protected lands).

Going forward, Vermont’s nonprofits will play an increasingly important role in land conservation, especially in continuing to protect those areas that are rich with species diversity.  Nonprofits are engaging more and more deeply in restoring wetlands that were previously degraded, planting new forests along river shores, and protecting unique natural communities while also protecting working forests and farmland.

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.

The State Of The Climate

By Leave a Comment

The federal government has issued the annual State of the Climate report and it is a sobering one.  The report states that carbon dioxide in the atmosphere rose to levels the world has not seen in at least 800,000 years.  Global carbon dioxide concentrations reached a record 407.4 parts per million during 2018.  That is 2.4 ppm more than 2017.

Other greenhouse gases like methane and nitrous oxide also continued their rapid increase.  Taken together, the global warming power of greenhouse gases was 43% stronger than it was in 1990.

Along with greenhouse gases, global sea levels also reached their highest levels on record for the seventh consecutive year.  Ocean levels are rising about an inch per decade, but that number may rise if ice melt at the poles continues to accelerate.

Global temperatures had their fourth highest level on record in 2018, slightly lagging 2016, 2015, and 2017 for the highest ever.  A La Niña over the Pacific cooled ocean waters for part of 2018, keeping temperatures a bit lower.  So far, 2019 is on track to be the warmest year in recorded history.

Global sea temperatures also set a record level in 2018.  And glaciers continued to melt at an alarming rate for the 30th consecutive year.

The State of the Climate report is yet another in a series of expert, science-based reports that continue to sound the alarm about the climate crisis.  Climate change is affecting our weather, agricultural productivity, water supply, public health and national security.  Unfortunately, the facts continue to be drowned out for many people by blogs, pundits, and posts on social media.

An Internal Price On Carbon

By Leave a Comment

As the world looks to reduce carbon emissions, many companies are dealing with paying for their carbon emissions as part of the cost of doing business.  But apart from the situations in which companies already are required to pay for their carbon emissions, a growing number of companies now build carbon pricing into their business plans even if they are not yet directly paying for their emissions.  This practice is known as putting an internal price of carbon into their business plan.
