Two Million Solar Installations

July 1, 2019 By EarthWise Leave a Comment

Three years ago, we reported that the United States had installed its one millionth solar energy system, a feat that took 40 years to accomplish. Recently, the Solar Energy Industries Association announced that there are now more than 2 million U.S. installations.

Analysts forecast that there will be 3 million installation in 2021 and 4 million in 2023.

California continues to lead the nation in installing solar power. More than 50% of the first million installations were in that state and California accounted for 43% of the second million. Its share is nevertheless slowly dropping with the growth of the residential solar sector that is rapidly diversifying across state markets. Some places have seen extremely rapid growth. In South Carolina, there were barely more than 1,000 cumulative installations in 2016; today, the state is home to more than 18,000 solar systems and expects to add 22,000 more over the next five years.

The five leading states in terms of number of solar installations are California, Arizona, New York, New Jersey, and Massachusetts. Other states recently seeing rapid growth in solar installations are Texas, Utah, Florida, Rhode Island and Maryland. Looking ahead, Illinois is forecast to grow from only 4,000 installations today to nearly 100,000 by 2024. The top ten state markets apart from California expect to add nearly 750,000 installation over the next five years.

The United States is at least the third nation that is home to more than 2 million solar installations. (Australia hit the milestone late least year and Japan actually topped 2 million in September 2014).

According to forecasts from analyst first Wood Mackenzie, by the year 2024, there will be on average one new solar installation every minute.

The Changing Face of Electricity

March 15, 2019 By EarthWise Leave a Comment

The New York Times recently published an article on how electricity is made in the United States on a state-by-state basis and how it has been changing over the past two decades. Two conclusions to draw are that the mix of energy sources is wildly different from one state to another and that the mix has been changing rather dramatically in many places.

Overall, the past two decades have seen the dramatic rise in the use of natural gas and a dramatic drop in the use of coal. Coal plants used to account for over half of the electricity produced in the U.S. at the turn of the 21st century. Now natural gas has passed coal as the largest energy source at roughly 1/3 of the total generated.

Switching from coal to natural gas is a good thing since modern gas power plants emit only about half the carbon dioxide as modern coal plants. But industry spin about “clean gas” is just spin. Gas is not really clean; it is just cleaner than coal. So, having the electric grid powered by gas is not really going to solve our emissions problems.

That being said, there are still states that make nearly all their electricity with coal. Indiana, Kentucky, Missouri, Utah, Wyoming, and West Virginia are on that list. Meanwhile, Delaware, Massachusetts, Mississippi, Nevada, and Rhode Island are powered mostly by gas. Idaho, Oregon, Washington, and Vermont rely heavily on hydropower.

Newer renewables like solar and wind are starting to make major contributions in many states. Wind contributes only 6% nationwide but is much bigger in places like Iowa, Kansas, Minnesota, the Dakotas, Oklahoma and Texas.

The face of electricity continues to change.

New Jersey Wind

May 24, 2018 By EarthWise Leave a Comment

New Jersey may host the second commercially operating offshore wind farm in the U.S. as soon as 2020. The company EDF Renewable Energy is moving forward with a plan to bring online a 24-MW farm sited off the coast of Atlantic City.

U.S. Offshore Wind Powering Up

February 26, 2018 By EarthWise Leave a Comment

After many years of false starts and delays, the offshore wind industry in the U.S. finally seems to be gaining momentum. According to the Department of Energy, more than 25 offshore wind projects with a generating capacity of 24 gigawatts are now being planned. Most of these are off of the Northeast and Mid-Atlantic coasts.

Renewable Energy Trends

There are major trends going on in the renewable energy world. Several will merit close attention this year.

New York Steps Up

August 14, 2017 By EarthWise

Now that the Trump administration announced that the United States would cease implementation of the Paris Climate Agreement, various state, local and corporate entities in this country have been stepping up to assume climate leadership.

Offshore Wind Progress

July 14, 2017 By EarthWise

Last December, the first commercial offshore wind farm in the United States started operation off the coast of Rhode Island. The Fisherman’s Energy Atlantic City Windfarm off the coast of New Jersey is under construction. With the lengthy logjam finally broken, there is increasing activity in the emerging U.S. offshore wind sector.

Surging Wind Power In The U.S.

June 16, 2017 By EarthWise

So far, it has been a big year for the U.S. wind industry, which experienced its fastest first-quarter growth since 2009. In total, about 2,000 megawatts of new capacity was installed, enough to power about 500,000 homes. With this addition, wind now produces 5 1/2% of the country’s electricity.

Wind Surpasses Water

March 21, 2017 By EarthWise

For many decades, hydroelectric dams were the top source of renewable energy in the United States. But for the first time ever, by the end of last year, installed wind power capacity in the U.S. outpaced hydroelectric capacity.

2016 Carbon Progress Report

February 22, 2017 By EarthWise

Last year was a big year for progress in the U.S. power sector. Renewable energy provided nearly 17% of the country’s electricity, up from 13.7% in 2015. The first offshore wind farm in the U.S. opened off the coast of Rhode Island. And most significantly, carbon emissions from the power sector continued to decline and reached the lowest levels in nearly 25 years.

Floating Wind

December 6, 2016 By EarthWise

Offshore wind power can supply a significant amount of energy to our hungry grid. In many places in Europe, it is doing just that. Here in US, it is just starting to be used in some places in the Northeast, with the first small offshore wind farm coming on line off the coast of Rhode Island.

Offshore Wind In Europe

November 28, 2016 By WAMC WEB

The U.S. has just turned on its first offshore wind farm off the coast of Rhode Island. In the meantime, offshore wind continues to grow by leaps and bounds in Europe. Wind energy in the European Union accounts for 12% of its electricity supply. Until 2011, offshore wind comprised only 5-10% of the newly-installed wind energy capacity; now it about one third of the new installations.

A Blueprint For Offshore Wind In N.Y.

October 18, 2016 By WAMC WEB

The Cuomo Administration recently released the New York State Offshore Wind Blueprint, a plan to advance the development of offshore wind along New York’s coastline.

Offshore Wind At Last

September 1, 2015 By EarthWise

At the end of July, construction began on the first offshore wind installation in the United States. The Block Island Wind Farm is being built off the coast of Rhode Island and is expected to come online next year, providing electricity for about 17,000 homes.
