What could be better than an outdoor shower? If your answer is a solar powered hot water shower that you built all by yourself (or with friends), read on. How to build a DIY outdoor solar shower Building an outdoor solar shower is a really effective way to lower utility bills, and it even frees up some bathroom…

Imagine charging your phone with the heat from your morning coffee. With the Epiphany onE Puck you can. The idea behind the Epiphany onE Puck is simple: use a Stirling engine powered by heat disparities (a hot or cold drink, a candle, ice, etc.) to fully charge your cell phone. Invented in the early 1800s, Stirling…

Belgium's offshore wind power reservoir uses excess power to pump water, storing it as latent hydroelectric power. One of the biggest drawbacks to renewable energies like wind and solar, is that it is unpredictable. This presents a challenge to grid operators, as they struggle to meet demand while compensating for…

An introduction to the math behind the placement of solar panels to optimize your yield, and speed up your return on investment. There is a lot you can do in home construction to take advantage of the free energy provided by the sun. That can be passive solar , which is about home orientation and window design to…

The inside of city water mains has up to this point not been a newsworthy place. With in-pipe power generating turbines, that is now poised to change. Hydroelectric power generation is definitely renewable but not always 'green' when you consider all the side effects, especially when it comes to large hydroelectric…

Electricity is clean at its destination but can be very dirty at its source. Not all of us have the means to install solar panels or wind turbines, but with the help of Bullfrog Power you can live a greener lifestyle hassle-free. Bullfrog’s green electricity comes exclusively from wind and hydro facilities that have…

Renewable power sources such as sun and wind present challenges for grid operators in being able to consistently meet demand. Tidal and river generators remove that unknown, and Cornwall, Ontario will soon benefit from a river turbine pilot project. A project started in 2002 by Verdant Power Inc. saw tidal turbines…

It has been estimated that the sun provides as much energy in 15 minutes as humans use in a year. By taking advantage of that with heating and electrical generation, we can work to end our dependence on fossil fuels. How to set up a home solar energy system Our future truly depends on us continuing to develop and…
