Solar energy on federal land

By Leave a Comment

Officials at the federal Bureau of Land Management announced late in August that they had finalized a plan to add Oregon, Idaho, Montana, Washington, and Wyoming to the Western Solar Plan, which started during the Obama era.   The plan, created in 2012, provides permitting for solar projects on federal land.  The original plan included Arizona, California, Colorado, Nevada, New Mexico, and Utah.

The Western Solar Plan is a major expansion for clean energy production in the Bureau of Land Management’s land leasing portfolio.  For decades, the BLM has leased tens of millions of acres of federal land to fossil fuel companies for oil, coal, and natural gas exploration and production.

The new addition includes 1.1 million acres of land in Oregon, an area larger than the entire state of Rhode Island.  The land selected is deemed to be of low risk for any adverse environmental effects from solar installation, and the plots of land are all within 15 miles of existing or planned electrical transmission lines.  A little over 50% of Oregon’s land is owned by the federal government and is managed primarily by the Bureau of Land Management and the U.S. Forest Service.

The publication of the finalized plan at the end of August initiated a 30-day period for any participants in the initial planning to voice objections.  The governors of the 5 new states are reviewing the plan.  Final approval and adoption are expected later this year.

Western states need to expand solar and other clean energy production to meet their climate goals and federal lands will have to play an important role.

Revolution Wind installs first turbine

By Leave a Comment

Revolution Wind is an offshore wind farm being built by Rhode Island and Connecticut and is the first multi-state offshore wind farm in the United States.  Once completed, it will deliver 400 MW of power to Rhode Island and 304 MW of power to Connecticut.

Revolution Wind is a 50/50 partnership between Ørsted, the Danish multinational energy company, and Eversource, a major New England utility company.  The wind farm is located about 15 miles south of the Rhode Island coast and 32 miles southeast of Connecticut.  It is fairly close to the recently completed South Fork Wind, the first completed utility-scale offshore windfarm in the U.S. and was built by the same partnership.

The first Revolution Wind turbine was installed at the end of August and construction continues with the installation of foundations for the 65 turbines that will comprise the project.  More than three-quarters of the units were in place by the beginning of September.  Ships have also arrived on scene for cable-laying operations for the wind farm.  Onshore construction continues in North Kingstown, Rhode Island, on the project’s transmission system.  The turbines for the project are being assembled by local union labor in New London, Connecticut. 

Commercial operations at Revolution Wind will not begin until 2026.  Construction of the electrical substation necessary to connect the project to the regional electric grid is taking place on the site of a decommissioned naval air station and it is a time-consuming project because of the presence of buried waste and soil contamination.  The construction of the offshore wind farm itself will be completed in 2025.

Offshore wind and the wake effect

By Leave a Comment

Electricity demand in the U.S. continues to grow and, in the summer, homes and businesses crank up their air conditioning which drives demand even further.  Many East Coast cities are banking on offshore wind projects that are underway in the Atlantic Ocean to help meet that growing demand.  The first offshore turbines are now producing power off the coasts of Massachusetts and New York.

Electric power utilities need to know how much power they can get from offshore wind farms, and this is not that easy to predict.  Wind is variable, so there is some built-in uncertainty.  But there is also a phenomenon known as the wake effect to contend with.

When wind passes through a series of giant turbines, the ones in front extract some energy from the wind and, as a result, the wind slows down and becomes more turbulent behind the turbines.  So, the downstream turbines get slower wind and may produce less power.

A study by the University of Colorado has modeled this phenomenon for planned wind farms in the Atlantic Coast region and has found that power output could be reduced by over 30%.  Researchers are installing weather monitors and radar sensors in islands off the New England coast to better understand the behavior of the wind in the area and improve prediction models.

The New England grid covers Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. Even with the wake effect, offshore wind is predicted to be able to provide 60% of the electricity needs of the grid, but it is important to be able to accurately predict what it can produce.

Offshore Wind In Maine | Earth Wise

By Leave a Comment

There are currently only two small offshore wind farms operating in the United States, but there are now several more under construction or in the permitting process.  Substantial wind farms are expected to come online over the next five years off the coasts of Virginia, New Jersey, Massachusetts. North Carolina, Delaware, Rhode Island, and New York.   There has been a recent auction for offshore wind sites off the California coast as well.

In April, the Bureau of Ocean Energy Management issued its Gulf of Maine Call for Information and Nominations, inviting public comment and assessing the interest in areas offshore of Maine, New Hampshire, and Massachusetts.  This is the first official step in the lengthy process that leads to offshore wind development in new areas.  Last year, the Department of the Interior defined an area of about 13.7 million acres in the Gulf of Maine that could end up providing energy leases for windfarm development.

The Biden administration has set a goal of deploying 30 gigawatts of offshore wind electricity generation by 2030, which is enough to power more than 10 million homes. It would also create thousands of jobs across manufacturing, shipbuilding, port operations, construction, and other industrial sectors.  Existing offshore wind projects have been structured to develop American-based supply chains for the offshore wind industry.

The European Union currently has over 15 gigawatts of installed offshore wind, has a target of 60 gigawatts by 2030, and 300 gigawatts by 2050.  The EU has five substantial sea basins which have tremendous potential for wind energy generation.  As a result, offshore wind is the centerpiece of the ambitious European Green Deal.

Here Come The Lanternflies | Earth Wise

By Leave a Comment

The spotted lanternfly is an invasive pest from Asia that primarily feeds on tree of heaven, which is itself an invasive species that has become widespread.  The real problem is that the lanternfly can also feed on some 70 other plants such as grapevines, maples, fruit trees, and more.

The lanternfly was first discovered in the US in Pennsylvania in 2014 and has since spread to 14 states including New York, Massachusetts, Connecticut, and Rhode Island.  (It was first spotted in New York in Staten Island in 2020 and has continued to spread).

The insect poses a significant threat to New York’s agricultural and forest health. Both the adults and nymphs feed on the sap of plants which stresses them making them vulnerable to diseases and other insect attacks.  They also secrete a sticky substance that attracts molds and interferes with photosynthesis.

Lanternflies are not strong fliers.  They mostly spread through human activity by laying their eggs on vehicles, firewood, outdoor furniture, and other objects that people transport.

The bout of unusually warm weather that the Northeast experienced in early spring is likely to have jumpstarted the spotted lanternfly timeline and hatching could be bumped up to as early as May.

Agriculture officials are asking for people to look for spotted lanternfly egg masses and scrape them off with implements with a sharp edge.  Adult insects should be reported to local authorities and should be killed if at all possible.  There is lots of information online about how to recognize the egg masses and the insects.  Spotted lanternflies are not a direct threat to humans, but they have the potential to cause great harm to vineyards, orchards, and forests.

Climate A Winner In The Elections | Earth Wise

By Leave a Comment

The dominant issues in midterm elections in November were the economy and abortion rights, but at the same time there were also ballot initiatives in various cities and states across the country related to climate.  What some describe as the ‘silent surprise’ of the election was that these initiatives generally passed and, in some cases, by large majorities.

The most significant of these ballot measures was in New York, where two-thirds  of voters passed the largest environmental bond measure in state history.  The measure funds up to $4.2 billion for environmental improvement projects including increasing flood resiliency, reducing greenhouse gas emissions, electrifying school buses, and creating more green and open spaces.

The Clean Water, Clean Air, and Green Jobs Environmental Bond Act provides up to $1.5 billion for projects aimed at climate change mitigation.  Another $1.1 billion is targeted for flood risk reduction and waterway restoration.  $650 million goes for water quality and infrastructure improvement. 

Rhode Island voters passed a green bonds act that will allow the state to invest in climate resiliency at the municipal level, as well as local recreation, open space protection, brownfields remediation, and forest and habitat restoration. 

Other climate-related ballot measures passed in Boulder, Colorado and in El Paso, Texas.  There were however a few climate measures that lost.  Proposition 30 in California that would have taxed very high-income residents to encourage sale of electric vehicles failed.  So did Arizona Proposition 310, which would have increased sales taxes by 0.1% to fund fire districts.

But overall, it was a good election for the climate.

Climate Change And Hurricanes In The Northeast | Earth Wise

By Leave a Comment

According to a new study led by Yale University, more hurricanes are likely to hit Connecticut and the northeastern U.S. as global warming continues to increase temperatures in the region.

Hurricane Henri made landfall in August as a tropical storm on the Connecticut/Rhode Island border.  In September 2020, subtropical storm Alpha made landfall in Portugal, the first subtropical or tropical cyclone ever observed to make landfall in the mainland of that country.

Tropical cyclones, hurricanes, and typhoons are typically intense and destructive in the lower latitudes. 

The study concludes that violent storms could migrate northward in our hemisphere and southward in the southern hemisphere as a result of warming caused by greenhouse gas emissions.

The research predicts that tropical cyclones will likely occur over a wider range of latitudes than has been the case on Earth for the last 3 million years.

In Connecticut, Hurricane Henri was not the only tropical storm to affect the region in 2021.  The remnants of Hurricane Ida brought damaging winds and torrential rain that felled trees and flooded streets and basements.

The northern expansion of such violent storms is going on as water levels in the Atlantic Ocean and Long Island Sound keep rising.  Because of melting glaciers thousands of miles away, water levels in Long Island Sound could rise by as much as 20 inches by 2050, enough to submerge parts of Groton’s shore and cause regular flooding in roads and neighborhoods.

Future hurricane prediction is an inexact science, but the ongoing trends do not bode well for the region.

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.

The Coastal Northeast Is A Hotspot | Earth Wise

By Leave a Comment

Global warming is, obviously, a world-wide phenomenon.  When the concept of a 2 degrees Celsius temperature rise is discussed, it refers to the average global temperature and the effects that would have on such things as sea level rise and weather patterns.  But the effects of the changing climate are not homogeneous.  Very different things can happen and are happening in different places.

One such place is the coastal northeastern United States, which is a global warming hotspot.  The region is heating faster than most regions of North America and, indeed, 2 degrees of summer warming has already happened in the Northeast.

New research led by the University of Massachusetts Amherst has determined that this heating is linked to significant alterations in the ocean and atmospheric conditions over the North Atlantic.

Several studies have found that the Atlantic Meridional Circulation is slowing down.  The AMOC conveys warm, salty water from the tropics north towards Greenland, where it cools and sinks.  The cooled water than flows back south as deep-water currents.  As the warming climate melts glaciers in Greenland, the circulation slows down, less cooled water arrives in the south, and there is more heating of the ocean off the Northeastern coast.

At the same time, the North Atlantic Oscillation, a weather phenomenon that governs the strength and position of the winds that blow from the U.S. over the Atlantic, has tended to settle into a pattern that enhances the influence of ocean air on the eastern seaboard climate.  Warmer ocean air being blown over the region has led to rising temperatures in Boston, New York, and Providence, Rhode Island.

As the average temperature of the world rises, some places will warm more quickly and others more slowly.

Is U.S. Offshore Wind Finally Happening? | Earth Wise

By Leave a Comment

Offshore wind capacity has been growing rapidly in recent years, especially in Europe and China.  Globally, there is now more than 30 GW of offshore wind and industry experts predict that there will be well over 200 GW of installed capacity by 2030.

Meanwhile, the U.S. has only two small pilot projects, one with five turbines off Rhode Island and another with two turbines off Virginia.  But after many years of battles with determined opponents, false starts, regulatory struggles, and other hurdles, the U.S. offshore wind industry appears to be poised to take off.

A combination of significant commitments by power companies to purchase offshore wind power, strong support by the Biden administration, and billions of dollars in investments is creating the new-found momentum.

New York, New Jersey, Virginia, Massachusetts, Connecticut, Rhode Island, and Maryland have collectively committed to buying 30 GW of offshore electricity by 2035.  (That’s enough to power roughly 20 million homes).

Among the first major offshore installations to be completed in the next few years in the U.S. will be Vineyard Wind, 15 miles off of Martha’s Vineyard, another wind farm 60 miles east of New York’s Montauk Point, a third fifteen miles off Atlantic City, New Jersey, and a fourth off the Virginia Coast.

Offshore wind projects will create nearly 40,000 jobs just in the New York-New Jersey area over the next ten years.  There is still some opposition from elements of the commercial fishing industry and from some coastal residents.  However, with state and federal governments committed to reducing carbon emissions and rapidly reducing regulatory barriers, and with the price of offshore wind continuing to get lower and lower, most observers agree that the U.S. offshore wind industry is finally on the verge of really getting going.

A Giant U.S. Offshore Wind Project Begins | Earth Wise

By Leave a Comment

In recent years, the Bureau of Offshore Energy Management – the agency that oversees energy projects in federal waters – has been granting leases for offshore wind projects in the waters of multiple states on the East Coast.  Up until now, none of these leases have actually resulted in the deployment of any wind turbines because the process of gaining approvals, project plans, surveys, funding and other requirements is a long and tortuous one.

In late May, the first offshore wind turbine in U.S. federal waters was installed 27 miles offshore from Virginia.  The 6-MW Siemens turbine is one of two turbines making up the Coastal Virginia Offshore Wind pilot project.  The pilot project is expected to be operational later this year.  This project is the first to receive go-ahead approval by the BOEM.

The CVOW project is a development by Dominion Energy, a Virginia-based utility that operates in 20 states.  Dominion’s project will eventually be a 2.64 GW mega-farm that could be the largest offshore wind farm in the world.  Construction of the main project is expected to begin in 2024.  It will be sited in the seabed of a 112,800-acre lease area.  The site is currently being surveyed to determine potential impacts to ocean and sea life.

Dominion Energy has made multiple commitments to emissions reduction and the massive offshore wind farm is an important part of its efforts to meet those commitments.  The CVOW pilot project is only the second offshore wind installation in the U.S.  The first, the Block Island Wind Farm in Rhode Island, is in state waters and did not require BOEM approval.
