A windmill is one of the most energy efficient and ingenious ways ever devised to pump water from the ground. A windmill harnesses the free and renewable power of the wind and uses that energy to lift underground water to the surface for agricultural and other uses.

Because windmills are so efficient and durable, the basic design hasn’t changed in almost 120 years. The secret lies in the way a windmill harnesses the wind’s energy to power a n ingenious water pump located deep underground.

… radiation warms the earth, different materials absorb the heat at different rates. For instance, water heats much more slowly than rock, and ice and snow even less than water since it reflects much of the energy back into space. Generally the darker material warms faster, and as it warms, the heat in turn warms the air above it, which then rises. Remembering our basic physics lessons, warm air rises, leaving a void for the cool air to then rush in and fill. This movement we call wind. So really, wind power is really solar power in a different form.

We can harness wind power by getting the motion of the air to in turn move a rotor, which generates electricity. …

Solar Water Heating

Today, most American homes and businesses use natural gas, electricity, or oil to provide them with hot water. The amount of energy required to meet our hot water needs is not insignificant. According to the U.S. Department of Energy (DOE), heating water today accounts for up to 14 percent of the average household’s energy use, and nearly four percent of total U.S. energy consumption. With electricity and natural gas prices continuing to rise, the costs of having a constant supply of hot water can really add up.

Solar water heating (SWH) technologies are a …

… now that talk about RE and none of them talk about how to do it on “the cheap” and still keep it simple. There are some great wind turbine do it yourself books that talk about hand carving blades out of wood and how to make your own generator from scratch. This includes even winding your own coils, welding, etc. But still, this is cheap but not very simple.

I believe there is too much waste in the world right now. I love the concept of taking something labeled as “junk” and making it new again. I hate to see batteries go to scrap when it is easy to get some more life out of them. Imagine all that lead and …

… and recycling rates remaining dismally low. The number of plastic bottles produced by the bottled water industry and subsequently discarded by consumers has only exacerbated this problem.

According to a 2001 report of the World Wide Fund for Nature (WWF), roughly 1.5 million tons of plastic are expended in the bottling of 89 billion liters of water each year.

Besides the sheer number of plastic bottles produced each year, the energy required to manufacture and transport these bottles to market severely drains limited fossil fuels. Bottled water companies, due to their unregulated use of valuable resources and their production of …

Electric water heaters, just like air conditioners, can be controlled by utilities to cut peak power demand.

But unlike air conditioners, pool pumps, clothes dryers or refrigerators, water heaters can also store energy in the form of hot water – and that could make them additionally useful in storing renewable power from such intermittent sources as wind farms.

Those are some of the conclusions of a new report from the Peak Load Management Association, a group representing utilities, smart grid, demand …
