Global Food Security Threatened By Rising Temperatures

Heat waves clearly can destroy crop harvests. The world saw high heat decimate Russian wheat in 2010. Crop ecologists have found that each 1-degree-Celsius rise in temperature above the optimum can reduce grain harvests by 10 percent. But the indirect effects of higher temperatures on our food supply are no less serious. Rising temperatures are […]

Geothermal Power Heating Up Worldwide

Iceland’s Nesjavellir geothermal power plant By J. Matthew Roney In 1904, Italy’s Prince Piero Ginori Conti became the first person to use thermal energy from within the earth to turn on the lights — five of them, to be precise. Now, more than a century after his experiment, 24 countries are using geothermal power. The […]

Ground Heat Source Pumps

How Do They Work? Ground source heat pump systems do not heat a home by burning fuel. They collect heat from the Earth via a pipe or pipes buried in the ground. These pipes are called loops and contain a mixture of water and antifreeze. The fluid is circulated through these loops by an electric […]

Geothermal Energy

We can generate geothermal energy by drilling deep holes into the earths crust pumping cold water through one end and then by the time it rises back to the surface the water can be hundreds of degrees Celsius which we then use as steam to drive a turbine which drives a generator creating power. Geothermal […]
