Seems like every time we turn around, the Department of Energy is making another announcement about our nation's energy future (if you believe that most cars will eventually be electric, these announcements are about our automotive future as well). Just a few days ago, we told you about the DOE's promising investment of $62 million into concentrating solar technology. Good news. Then we told you about the DOE's request for commentary on squeezing the last precious drops of fossil fuels from the
Tapping some of the enormous amounts of thermal energy that emanates from deep within the earth is one of the more promising methods of renewable power. Unlike wind and solar, geothermal tends to be a lot more consistent than the sun or flow of air. It now looks like geothermal power could have another potential benefit: waste water from at least one geothermal plant in central California is rich in lithium.
In order for electric vehicles to make any actual impact on greenhouse gas emissions, a great deal of progress will need to be made on renewable sources of power generation. Wind power generation has been expanding rapidly, and solar is growing in some areas. Another source with huge potential is geothermal. If the natural heat energy held within the planet can be tapped, it could be almost limitless. That's easier said than done in most places but there are some areas where it could be very pra
Iceland doesn't have any fossil fuel resources of it's own, but it has no shortage natural energy from deep within the earth. Thanks to abundant volcanic activity from the mid-Atlantic ridge, there is plenty of geothermal energy available. This has provided Iceland the opportunity to try and completely eliminate the import of fossil fuels over the next few decades.
A newly announced biodiesel plant in Nevada will use a geothermal energy source. The plant, to be built by Infinifuel (cool name, that) will build the biodiesel plant as part of facility that generates 5 MW of electricity from two production geothermal wells and seven power production units, while the 220 degree steam will be used in the production of biodiesel. All of this geothermal power will be able to produce five million gallons of biodiesel a year, made from oilseed and/or algae (Infinifu
