Last New York Coal Plant Closing | Earth Wise

April 13, 2020 By EarthWise Leave a Comment

The last coal-fired power plant in New York State is closing. The plant, located in Barker, about an hour’s drive from Buffalo, employs 44 people. The plant’s closure is an early test of New York’s new climate law, which is one of the most ambitious in the country. The law is supposed to transform the state’s energy grid to carbon-free by 2040.

Coal plants across the country are going offline, priced out by natural gas and targeted by regulations and incentives aimed at reducing greenhouse gas emissions. Coal plant closures bring common challenges: lost tax revenues and jobs as well as efforts to retrain workers and clean up sites. Every plant has a specific place in a community, and each community has its own story.

The new climate law is supposed to create thousands of new jobs, including high-paying union jobs like the ones the employees in Barker are losing. But jobs are scarce in the northwest corner of the state where Barker is located.

The state government has recently issued rules that would make it easier to get permission to build renewable energy sites, including wind turbines and solar farms, allowing applicants to bypass zoning rules and other local regulations. But residents of rural towns have environmental and aesthetic concerns about these potential new energy plants.

In 2010, the United States had 580 coal-fired power plants providing 45% of the country’s electricity. By March 2018, there were fewer than 350 plants and coal’s market share had dropped to 30%. At this point, there are about 224 plants producing 18% of the country’s power. The writing is on the wall for coal power.

Utility-Scale Solar On The Rise

May 8, 2019 By EarthWise Leave a Comment

According to research from Goldman Sachs, utility-scale solar power capacity is expected to grow by double digits globally over the next two years. The growth will be driven by expanding use of the technology in the United States, Europe, the Middle East, and China.

Solar power is the world’s fastest growing source of electricity generation and is slowly taking market share from fossil fuels like coal and natural gas. The transition is being driven by a combination of continuously lower prices for solar power and the impact of policies aimed at reducing emissions.

Utility-scale solar is defined as installations designed solely to feed electricity into the grid, in contrast to smaller-scale residential or commercial building units. There are now solar farms larger than half a gigawatt in generating capacity. According to the Goldman report, global utility-scale solar installations will reach 108 gigawatts in 2019, up 12% over the previous year, and will then grow another 10% to 119 gigawatts in 2020.

When residential and other smaller installations are included, most analysts expect global solar power capacity to soon hit 600 gigawatts. To put this in perspective, the global capacity only reached 100 gigawatts in 2012 and was actually less than 10 gigawatts in 2007.

Even more dramatic than the growth of solar installations is the reduction in solar cost, and the two are obviously closely related. Solar panel costs have dropped from around $70 per watt of electricity generated in 1980 to 36 cents per watt currently in the United States. When favorable policies both from governments and related to corporate sustainability targets are added to the mix, the booming growth in solar power is easy to understand.

More Power From The Sun’s Heat

November 29, 2018 By EarthWise Leave a Comment

When we think of solar power, we usually are talking about the panels that generate electricity using the photovoltaic effect. These panels are on millions of rooftops around the world and in utility-scale solar farms. There are also solar water heating systems that use the sun’s heat to provide hot water for homes and businesses.

Farming In Solar Farms

March 19, 2018 By EarthWise Leave a Comment

Utility-scale solar installations have been expanding rapidly. The amount of land used for solar projects is becoming quite substantial. The National Renewable Energy Laboratory (NREL) predicts that 3 million acres will be devoted to solar farms by 2030, and 6 million by 2050. These numbers pale in comparison with the land used for corn, soybeans, and wheat, but are more than used for such familiar crops as oats, barley and rice.

The End Of British Coal

November 3, 2017 By EarthWise Leave a Comment

In the 19th century, Britain produced 80% of the world’s coal. Britain was the dominant global power in the industrial revolution with its giant blast furnaces, steam locomotives and steam ships. And with advent of the electric age, coal once again was the power source of choice. Even as late as the 1970s, Britain got 80% of its electricity from burning coal.

Utility-Scale Solar Power

Solar panels on the roofs of houses have become a familiar sight in recent years, but utility-scale solar – installations of 10 megawatts and greater – are really booming these days. Throughout the United States, more than 10.5 gigawatts of utility-scale solar were added to the electric grid in 2016 – enough to power more than 2 million homes – and at least 8 gigawatts more are scheduled to come online this year.

Solar Power As A Crop

December 15, 2015 By WAMC WEB

The historic, relentless drought in California has caused a number of the state’s farmers to start planting photovoltaic panels instead of crops. Because of the drought, Federal water deliveries to farmers in the Central Valley and elsewhere have been dwindling. As a result of the water shortage, more than 500,000 acres will lie fallow this year.

New Places For Solar Power

October 22, 2015 By EarthWise

The modern face of solar energy is hundreds of thousands of rooftops covered with arrays of solar panels. It is also amazing expanses of solar panels and mirrors covering acres of desert land. Solar power capacity is expanding rapidly and is expected to at least triple over the next 10 years.

Solar Power And The Landscape

October 5, 2015 By EarthWise

The use of solar power is growing rapidly but with all the growth, solar power only provides 1% of the country’s electricity. On the other hand, in 2014, solar power accounted for almost a third of all the new US electric generating capacity. According to the International Energy Agency, solar power could be the world’s leading source of electricity by the year 2050.
