Large-scale geothermal energy relies on the heat and water that exists below the surface of the earth, but not everywhere has accessible naturally occurring hot water. A fairly recent technique called enhanced geothermal energy or hot dry rock geothermal energy … Continue reading →
I have written a few times before about the technological and financial hurdles facing the development of green hydrogen. Along the way, I mentioned specific companies working on hydrogen fuel cell projects. Hydrogen is not so much an energy source … Continue reading →
It has seemed for a long time that generating electricity from the sun and the wind would eliminate a lot of environmental problems. We would not have the pollution that comes from mining coal or extracting oil from the ground … Continue reading →
Waste-to-energy technology treats non-recyclable waste as a resource instead of a disposal problem. Whether solid, liquid, or even gas, waste has recoverable energy. It can provide heat, fuel, or electricity. Germany, the Netherlands, and the Scandinavian countries direct so much … Continue reading →
NASA has used liquid hydrogen as a fuel since the 1970s. It has seemed just around the corner for earthbound, civilian use almost as long. We can now create green hydrogen, which produces no waste except water. It’s expensive and … Continue reading →
This year’s hurricane and wildfire seasons have once again exposed weaknesses in our electric grid. Distributed energy resources and microgrids—especially solar microgrids—point the way to a better energy future. Why are power companies so reluctant to move in that direction? … Continue reading →
