Hoping to take advantage of its violent volcanic heritage, Iceland is contemplating building the world’s biggest undersea electric cable, so it can sell geothermal power to other European nations. If it works, it could export enough electricity to power 1.25 million homes.
Fifteen months ago, I set out to fulfill a lifelong ambition of building my own home using the latest green technology. On a $350,000 budget, several dreams came true. I installed a solar-powered boiler, a rooftop garden and a graywater recycling system. Other dreams were harder: A delivery truck damaged the recyclable foam panels meant to form the frame of my home, and I’m also considering suing my window contractor. But it will all be worth it when we move in next month. For those considering your own eco-haven, I offer four pieces of advice.
Any green home worth its weight in compost draws heavily on solar energy. Mine is equipped with all the standard offerings, such as a solar-powered boiler, the subject of my last column. Trouble is, the sun doesn’t always shine. So to make up the difference during cold, dark winters and rainy spells, I’m turning to another eco-friendly energy source: my backyard. The two 325-foot-deep geothermal wells I’m boring there will use the constant 50°F temperature of the Earth at that depth to meet all my extra heating and cooling demands.
Boston's Trinity Church, a landmark building, needed a new heating and ventilation system. The solution: a geothermal heat pump.

"The only place to go is down." That's what the congregation of Boston's Trinity Church decided. The landmark building, built in 1877, needed a new heating and ventilation system. Surrounded by public squares and huge high-rises (including the famed John Hancock Tower), the church has no backyard where builders could hide the unsightly equipment. After investigating a variety of technologies, the historic congregation-which has been meeting in various buildings since about 1735-decided to go with a geothermal heat pump (GHP).
