A Quiet Clean Energy Revolution

March 5, 2019 By EarthWise Leave a Comment

While the Trump administration seeks to prop up and promote use of fossil fuels, the country continues to move in the opposite direction.  Last year was actually a pretty positive year for clean energy in the U.S.

In terms of public opinion, 70% of Americans surveyed believe the country should produce 100% of its electricity from renewable energy sources and more than half of survey respondents think renewables are a good idea even if they raise energy bills.

Companies in the U.S. purchased a record 6.43 gigawatts of renewable power, enough to power 1.5 million homes.  The number of corporations entering into renewable energy deals doubled last year.

More than 300 U.S. cities, towns or counties have made commitments to climate action and, as of November, 99 cities have committed to 100% renewable energy, doubling the total from a year ago.

A number of gubernatorial candidates running on ambitious renewable energy platforms were elected in November including those in Illinois, Colorado, New Mexico, Maine and Nevada.

Utilities are responding to the growing demand for clean energy.  Consumers Energy in Michigan plans to cut carbon emissions by 80% and stop using coal.  Iowa-based MidAmerican Energy will become the first U.S. utility to source 100% of its electricity from renewable sources next year.  Xcel Energy, one of the biggest utilities in the country, has committed to be 80% carbon-free by 2030 and go completely carbon-free by 2050.

The fossil fuel industry with its supporters in high places is still kicking and screaming, but there is no doubt that the U.S. energy system is changing, and the quiet clean energy revolution will only pick up more steam in 2019.

Los Angeles has a tremendous thirst for electric power and is always trying to find new sources.  On December 1, the Los Angeles Department of Water and Power began buying all the power generated by the brand-new 24 MW Tungsten Mountain geothermal power plant located in Churchill County in Nevada’s Great Basin region.

A project planned for sunny South Australia will be the world’s largest single solar thermal power plant when it comes on line in 2020.   The Aurora Solar Energy Project will have a capacity of 150 MW, which is enough to supply 90,000 people with electricity.

Solar Power 24/7

The biggest challenge facing both solar and wind power sources is that they don’t produce power around the clock; they only work when the sun is shining or the wind is blowing.  As a result, they don’t quite measure up to the requirement for power on demand.

Storing Energy With Rocks

Energy storage is hot topic because more and more electricity is being generated from renewable sources like solar power and wind power that can’t operate all the time because the sun doesn’t always shine and the wind doesn’t always blow.  So we need ways to store surplus energy when it is produced and be able to use it later when it is needed.
