Volcano Power
Geothermal energy uses the heat trapped beneath the Earth’s surface to generate electricity. Typically, geothermal energy plants tap into the steam from natural sources such as geysers, or they draw water from hot, high-pressure underground sources. The hot vapors are then used to drive electric turbines.
2016 Carbon Progress Report
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.
Is Coal Coming Back?
The new administration has promised to revitalize the coal industry in the U.S. A major part of this plan is to eliminate various regulations that hamper that industry. But the truth is that coal has lost ground for far more important reasons than regulation.
Are Electric Cars Worth The Price?
Pretty much every discussion of electric cars, plug-in hybrids and ordinary hybrids starts and ends up with the question of whether they are worth the money. If the reason for buying such a vehicle is strictly economic, then this is the right question to ask. But the naysayers who say such a purchase is foolish may be barking up the wrong tree.
The Economics Of Renewable Energy
Very few people are against the use of renewable energy sources like solar and wind power in principle. It is hard to argue against generating power from resources that are free and plentiful. The main knock against renewable power sources has been that they cost too much compared with conventional, fossil-fuel technologies.
Old-School Companies And Renewable Energy
The biggest Internet companies have been embracing renewable energy for years now. The company that bought the largest amount of clean energy last year was Google, which has three times the renewable capacity of the next biggest user. Other familiar names in the top ten companies in total wind and solar capacity include Amazon, Facebook, Microsoft, and Apple. These companies have been ahead of the pack in looking for sustainable ways to meet their substantial energy needs.
