Guest blog by SA Shelley: No doubt about it, the world runs on energy (and money). Nearly 80% of all the world’s energy is still provided by coal, oil and gas though this fossil fuel proportion of the energy mix is now shrinking and in just under 10 years, the world’s energy mix will look markedly different. I hope that in addition to coal, oil and gas the OWOE reader is familiar with some of the other large energy sources such as nuclear, wind, solar, hydro and wave. Here at OWOE we try to bring useful and relevant knowledge and ideas about energy to the reader, and one big potential and virtually zero carbon energy source that has been overlooked by a lot of people including the OWOE bloggers is geothermal energy. Well no more. After a bit of research this OWOE blogger has gone gung-ho for geo for good reason.Continue reading Gung-ho for Geo
On August 21st a dedication ceremony at the Natural Energy Laboratory of Hawaii Authority in Kona was held to celebrate completion of the world’s largest operational ocean thermal energy conversion (OTEC) power plant. This was a major achievement for Hawaii, the U.S. and marine renewable energy. This test plant will generate 100 kilowatts of clean, continuous, sustainable electricity and is expected to be a stepping stone to larger plants that will be cost competitive options for electrical power for Hawaii and other island locations in Asia Pacific
OTEC uses the temperature difference between deep cold ocean water and warm surface water to boil liquid ammonia, which can then drive a turbine to generate electricity. It is estimated that ocean thermal energy conversion has the potential to generate over four times the total electricity usage of the planet.
