Booming U.S. Renewable Energy Sector Growing Faster Than Expected

The mainstreaming of renewable energy is happening even faster than projected.

According to the latest “Electric Power Monthly” report from the U.S. Energy Information Administration, which includes data through the end of 2014, some 13.91% of electricity generation in the U.S. last year was from renewable sources.

“Given current growth rates, especially for solar and wind, it is quite possible that renewable energy sources will reach, or exceed, 14% of the nation's electrical supply by the end of 2015,” noted Ken Bossong, executive director of the SUN DAY Campaign. “That is a level that EIA, only a few years ago, was forecasting would not be achieved until the year 2040.”

That number includes conventional hydroelectric power, which comes with severe environmental impacts of its own and is not generally considered a true “clean energy” source (the same can be said of biomass and biofuels, which is also included). So it’s worth noting that 2014 was the first year that electricity generation from non-hydropower renewable energy sources exceeded hydroelectric generation.

Wind energy continues to be the biggest clean energy source by far, supplying some 4.45% of 2014 electricity generation in the U.S. versus .45% from solar and .41% from geothermal. But solar is making great strides, seeing more than 100% growth last year while wind grew just 8.3% and geothermal by just 5.4%.

Top 5 Clean Energy Revolution Stories of 2014

The steady march of renewable energy, primarily wind and solar, toward mainstream usage continued apace in 2014.

Here are the top 5 clean energy revolution stories in the U.S. this year:

Top 5 Reasons Why Geothermal Power is Nowhere in Canada

geothermal energy potential in canada

Canada has no commercial geothermal power plants, despite having abundant potential and, ironically, Canadian energy companies running geothermal power plants around the world.

Canada’s west coast forms part of the Pacific Ring of Fire, a giant horseshoe of active volcanoes and earthquake zones stretching from New Zealand all the way around Alaska to the bottom of South America. The geology putting coastal cities at risk also makes the area great for developing geothermal resources.

Ring of Fire countries New Zealand, Indonesia, the Philippines, the United States and Mexico all have commercial geothermal plants, but not Canada. A groundbreaking 2010 study of Canada’s geothermal potential found the best locations were in British Columbia, Alberta and Saskatchewan, but even Ontario could produce geothermal power if someone dug deep enough.

To develop a geothermal power plant, a firm needs to drill a well deep into the ground to extract hot water to generate steam to turn an electrical turbine. The water is then recycled through another well back underground. The most important factors are the temperature of the extracted water and the flow rate – the hotter the water and the more of it, the better.

Why Is North America Behind The Curve On Climate Change and Energy?

Just three short years ago, it appeared that North America was on the verge of finally kicking that nasty dirty energy addiction that was crippling our economies and our energy independence.  The United States had elected a president (Barack Obama) who set incredibly lofty goals for renewable energy targets, and green energy investments across the continent were higher than anywhere else in the world.

U.S. Government Significantly Underestimating Costs Of Climate Change And Dirty Energy

A new study released today shows that the U.S. government is using faulty calculations and outdated information to determine the costs of energy and climate change in America. The study was written by Chris Hope from the University of Cambridge and Laurie Johnson of the Natural Resources Defense Council, and published in the Journal of Environmental Studies and Sciences.

Current government models would have us believe that fossil fuels provide the cheapest sources of electricity for the United States, but the new study says that the numbers being used are misleading, as they do not take into account all of the costs, specifically those related to climate change, that these sources of energy carry.
