Solar, wind and hydro power could soon surpass coal

by Matt Egan, CNN Business

Coal, long the king of America’s electric grid, will soon get toppled by renewable energy.

Solar and wind power are growing so rapidly that for the first time ever, the United States will likely get more power in 2021 from renewable energy than from coal, according to projections from the Institute for Energy Economic and Financial Analysis.

New Scientific Study Says Solar Can Already Generate More Energy Than Oil

by Lance Schuttler, The Mind Unleashed

Oil proponents have been saying for awhile now that solar doesn’t match up to oil’s energy output, but that statement may have just been proven false. In a major scientific study published in November 2016’s Renewable and Sustainable Energy Review, researchers looked at 29 separate studies and compared the solar photovoltaics (PV) generated as compared to the energy needed to create and install the panels.

The study compiled all the data from the 29 separate studies to gain a clearer picture of solar power’s energetic output. What they found was that only 5 of the 29 studies used recent data, which initially, showed a bleaker picture of what solar can actually generate. However, after compiling data with up to date technological advances in solar energy, the studies showed that solar can generate 14 times the power needed to create the panels.

The author of the study, Rembrandt Koppelar, who is a doctoral researcher at the Center for Environmental Policy, Imperial College London, said that oftentimes solar studies are using data that date back to as far as 1998. In other words, many studies put out there about solar energy, are using technological data that is many years old, and not up to date with current capabilities of solar energy output.

Six unexpected sources of renewable energy

Think: Las Vegas streetlights powered by footsteps

When it comes to discussions about renewable energy, solar and wind power often take center stage. To a lesser degree, other forms like geothermal energy and hydro-power also get some attention. But many people may not be aware that there are many other sources of renewable energy currently in use around the world, all helping to counterbalance the enormous carbon dioxide emissions from burning fossil fuels. Small projects are turning to dirt and microbes, underground stores of liquid magma and even pedestrian footsteps to harvest energy that would otherwise be wasted.
