As the name implies, biofuels are fuels derived from organic material. Since they can be made in many ways, they are classified as 1st generation, 2nd generation, and 3rd generation.
First generation bio-fuels are the more common fuels that are produced from food crops and animal fats. Some examples include bio-diesel, vegetable oil, and bio-gas.
Second generation [...]

Harnessing the power of water has been used for centuries for many useful purposes. Initially it was used for irrigation and operating various machines, such as windmills and dock cranes. But these days it has a more important use: as a renewable source of electricity.
So what is hydro power?
Well, basically it is the generation of [...]

Solar power energy systems are not inexpensive. That said it’s important to compare them within context of other types of home improvement projects. Home buyers and realtors view a solar photovoltaic or solar hot water heating system as a significant value-added improvement – similar to adding a deck or remodeling your kitchen. Plus unlike a [...]

Australia is planning to build the world’s largest solar power station, with three times the generating capacity of the California plant that has been the biggest to date.
Prime Minister Kevin Rudd said the photovoltaic plant would cost A$1.4 billion (US$1 billion) and will have an output of 1,000MW – equivalent to that of one coal-fired [...]

Technological advancements in wind energy efficiency have generally come incrementally and usually made via a process of increasingly large wind turbine blades. Put simply, the model has been: longer blades = more output per turbine.
But that pattern of incremental improvements may be a thing of the past if Leviathan Energy has anything to say about [...]

A new technology that was developed at the University of NSW allows traditional panels to catch more light from the blue end of the spectrum, the short wavelengths, and is expected to influence future panel production around the world.
Many existing solar panels end up reflecting back the shorter wavelengths of light due to a layer [...]
