Alternative Energy
Renewable Energy Technologies Explained
We’re constantly dealing with the threat of running out of fossil fuels, and with energy prices set to sky-rocket in 2012, it’s no surprise that so many people are looking to alternative sources of energy to heat and power their homes. But there’s so much jargon and confusion surrounding alternative energy sources, and that can make it difficult for people like you to make the right choice. That’s why we’ve put together this guide to alternative energy. It gives you information on all the different types of energy and heat sources available on the market, and advice on how you can bring these sources into your home.
1. Solar power
Solar power is generated when solar panels store light and/or heat energy from the sun. Advancements in solar power are happening all the time. In fact, quite recently, the PV solar panel was perfected.
A PV solar panel is created when sheets of silicon crystal with slightly different molecular structures are layered on top of one another to create a much more effective solar panel than we’ve ever had before. Solar panels were previously used solely to heat up water for our homes, but now they can be used to provide your home with electricity, too. Energy providers such as British Gas can provide you with solar power packages, which help you to switch over from mains electricity to solar power.
2. Wind power
Wind power can be generated on a small and an industrial scale. We’ve all seen images of the wind farms, with their huge posts and massive turbines, and these pump electricity straight into the National Grid.
Small wind turbines are available to buy from a number of different suppliers, and are appropriate for sticking in your back garden. Generally, these smaller wind turbines are used to recharge items rather than to power you whole house – think rechargeable batteries, and other portable household items. You can also use wind power generated at your house to power your central heating system.
3. Hydro-electricity
Hydro-electricity is generated when water moves downhill at a very high speed, turning turbines as it flows. Although it’s difficult to harness hydro-electricity on a small scale, like you can with wind power and solar power, it is possible, especially if you live in a highland area, or close to a body of water such as a river. If the body of water is big enough, you could actually become completely dependent upon hydro-electricity to power your whole home, and you would not need a mains supply at all.
4. Geo-thermal power
Geo-thermal energy is not as well-used as the first three types of sustainable energy, but it certainly has room for development. Geo-thermal energy involves using the naturally occurring heat from under the earth to create steam and to create electricity in a similar way to conventional power stations. The electricity gleaned from geo-thermal sources is usually used for central heating and hot water systems.
