It’s probably not a news flash that gas doesn’t seem to be getting any cheaper. People all over are asking what they can do about the rise in price, and often the answer is to choose a different vehicle. That’s simple, right? But what kind of vehicle should you choose? Just maybe, you should try [...]

Just where did a hybrid car get its start? Well, read on to find out. Hybrid cars are very popular for today’s car buyers, and there are many reasons why. But before you even think about choosing to buy a hybrid car, you might want to know a little bit about the history of a [...]

Biomass is the name given to any material which is recently derived from plants that use sunlight to grow, such as wood from forests, material left over from agricultural and forestry processes, and organic industrial, human and animal material. It is sometimes classified as ‘combustible renewables and waste’. The energy contained in biomass originally came [...]

The word geothermal comes from the Greek words geo (earth) and therme (heat). So, is a renewable resource originating deep within the Earth where temperatures can reach up to 6000°C. At a depth of five kilometres from the Earth’s surface, the temperature decreases to around 200°C. We can use the steam and hot water produced [...]

Wind power is the harnessing and conversion of wind energy into a useful form, such as electricity, using wind turbines. Wind energy has been used for thousands of years – to propel sailing ships or converted into mechanical energy to pump water or grind grain. Windmills are used in many countries (such as the Netherlands) [...]

The tides moves a huge amount of water twice each day, and finding an effective and economical way to harness that process could provide a great deal of energy. In fact, tidal power has potential for massive future electricity generation, as the tides are far more predictable than wind energy and solar power. However, although [...]

Wave power is the term used to describe the harnessing of the energy contained in the ocean’s surface waves, and converting that energy into a useful form – usually electricity generation. Wave energy is essentially stored, concentrated wind energy, the waves being created by the progressive transfer of energy from the wind as it blows [...]

Hydro power is the term usually applied to the power/electricity created from the force of running water. It is generally less expensive than the mining of fossil fuels and does not contribute to greenhouse gases and climate change. Unlike other alternative energy sources like the sun or wind, water can be stored which makes it [...]

Harnessing the power of the sun’s ray to create energy to power our house is very appealing. But the question is, “Is everything about solar energy good?” Looking at the current price of fossil fuel-based electricity, it is quite impractical to convert into solar energy system. However, with the growing concern on the state of [...]

Fuel cells are electrochemical devices that convert a fuel’s chemical reaction in an electrolyte directly into electrical energy from fuel (on the anode side) and an oxidant (on the cathode side). While they are similar to batteries in that they have no moving parts, batteries store their energy whereas fuel cells can produce electricity continuously [...]
