New weekly feature - the best of green

Each week, we'll feature the best green news story from the previous week. Join us to stay on top of what hot in the world of "going green" each Friday.

This week's story comes from Canadian journalist and blogger Tyler Hamilton. According to Hamilton,

A British Columbia-based company called Free Energy International has signed a deal with an undisclosed oil and gas exploration and production company in Alberta, in an area known as Swan Hills. Free Energy will build two 1-megawatt geothermal plants that take hot water — a co-product of oil and natural gas during the pumping process — and extract the heat from it to generate electricity. The $7 million project will tap wells that are around 9,000 feet deep, and temperatures of the fluids can easily reach 170 degrees F in high volumes. After the heat is extracted from the water using heat exchangers, it is used to run an Organic Rankine Cycle (ORC) power plant. The water is later pumped back into the ground. Free Energy will build, own and operate this binary cycle plant and the oil company has agreed to buy all the electricity produced for the same rate it was paying to a previous supplier.
