The Tectonic & Volcanic Events That Will Accompany The Melting Of The Ice Sheets —…

As the ice sheets of the world melt, an enormous amount of pressure will be lifted off of the continental crusts that play host to them, as well as the surrounding oceanic basins. Something similar is broadly true, but to a much lesser degree, of the world’s remaining large glaciers (think of the Himalayas).

Geothermal Plant Supplies ~20% of Hawaii’s Electricity

Living on active volcanic islands has its downsides and its upsides. When it comes to the plus side, there’s the potential to use geothermal energy to produce significant amounts of cheap, clean, renewable electrical power. And that’s what’s happening on the ‘Big Island’ of Hawaii, where Ormat Technologies’ Puna Geothermal Venture is producing about 20% of the electricity consumed on the island, which removes the need to buy and burn some 144,000 barrels of oil a year.
