As renewable Energy prices Fall, researchers tally their Additional Prices

Expand (charge: TLPOSCHARSKY / / Flickr) Renewable energy costs have dropped to the stage at which, for a lot of Earth, solar and wind energy is now less expensive than fossil fuel-generated power. However, the variability of the power sources might make handling them in an electrical grid hard –an obstacle which can precise prices […]
