We are used to the idea of powering our homes from our roofs, by now. But what if we could get our electricity from the basement? From what’s already down there… heating our homes.

Everyone who uses natural gas to supply heat and to heat water, could be tapping into that heat to make their own electricity as well with a CHP unit. Unlike solar or wind power, this energy source could be supplying electric power both day and night, and whether it’s windy or not.

And who better to make such a unit but an auto company that has already put in some design time making natural gas engines work more efficiently. Volkswagen wants to make electricity in your basement.

If you live in Germany. For now. Read the rest of this entry »

A surge in the number of mercury-bearing energy-efficient light bulbs in use in Minnesota is expected to overwhelm recycling programs in the next few years and there’s no plan yet on how to recycle more of them.

Fluorescent light bulbs use only one-fourth as much energy per unit of light produced as incandescent bulbs and last up to 10 times longer. One CFL bulb contains 5 milligrams of mercury, about one-fifth the amount in a watch battery.

The European Union is on the cutting-edge of green technology; already ahead of many nations through its introduction a ban of incandescent light bulbs that began on September 1, 2009. The ban of these incandescent light bulbs has a goal of reducing region-wide energy costs through use of the more eco-friendly compact fluorescent light bulbs instead.

Here’s a very good example of simple tech that works efficiently. Because hot air rises, cool air falls down. So if chilled water is carried through tubes at the ceiling, it sucks hot air from a room; sending down the cooler air. Simple tech is often low carbon technology too.

If you live in one of the states now sweltering through heat waves; even more frequent sweltering days are in your future as a result of climate change.

But it’s not only your children’s children who will suffer heat waves more often. Your property values in these states will also sink over time as your neighborhoods heat up to unlivable levels over the next decades.

A/C will be a necessity. But adding a heat recovery system will at least cut those losses to your home values:

The economy is down, but here is another sign that green technology may be the way out of our economic dilemma. US clean energy patents hit a record high last quarter.

If you want to cut your carbon footprint, you can ride your bike a little more. If you want to cut it even further (from all that exhaling while pedaling), meet the EniCycle. This one-wheeled ride has a range of just under 19 miles on a charge. But it recharges when you ride it downhill (if you dare).

In recent posts on Planetsave and EcoWorldy about moratoria on soya and cattle products related to Amazon destruction, it was mentioned that McDonald’s is helping to save the Amazon. With the company also delving into green building, progressive energy saving software, and charging stations for electric vehicles, is McDonald’s a green company?

Aug. 29 is the fourth anniversary of Hurricane Katrina and Kanye West’s “George Bush doesn’t care about black people” comment on live TV.

The rebuilding of New Orleans continues. And it’s being rebuilt in shades of green.

According to a “New Orleans Green Building Assessment” released by the Sierra Club, the devastation of 2005 has provided the city with a unique opportunity to develop a national model for rebuilding with sustainability in mind. Read the rest of this entry »

The summer of 2009 has been cooler than usual in the Midwest, but Mother Nature can still pack a punch.

August has seen some 90-degree days in places like Michigan.

When it get this hot, some people like to stay inside in front of the air conditioner (based on recent Twitter and Facebook updates). But it doesn’t have to be this way.

The air conditioner, I mean.

A “whole house fan” that uses the attic for venting can keep your home cool with less electricity (and for less money) than modern-day air conditioning. Read the rest of this entry »
