Author: It is feasible to generate electricity by making the greatest possible use of natural resources. Most renewable energy resources are derived from the sun and solar radiation, like energy for heating and electricity, as well as indirect forms of solar energy such as energy from the wind and waves, and geothermal energy resulting from the heat generated within the earth.
A renewable energy system is a specific technology that has been designed to make use of these self replenished resources. There are currently some really good systems available. However there are still technologies that require further research and development so that they can replace a significant amount of fossil fuel consumption, and hence cut down the overall environmental impacts from the use of such fuels and current energy sources.
The sun’s power can be converted into energy directly with a renewable energy system. There are a number of technologies in use at this point of time, but not too many people are using these technologies. One such renewable energy system is a solar technology known as `solar collectors`. These are meant for active solar heating, where a solar collector is set up on the roof of a building and gathers solar radiation, and produces heat at temperatures usually under 100ºC.
What is often the case is that people make use this renewable energy system for hot water to supply their home for heating up swimming pool and showering. There are a number of energy companies that deal in clean energy who will supply a solar collector for you at a charge, or if you are good with your hands and consider yourself to be a bit of a `handyman’, you can build the technology on your own using materials that you can buy at your local hardware store.
Solar collectors are a very simple renewable energy system. One of the better technologies that use the power of the sun’s rays is a solar thermal engine. These use the same idea as the solar collectors discussed above however the technology is much more advanced and thereby much more effective. This renewable energy system makes use of active solar heating at very high temperatures to propel steam to turbines, in order to produce high amount of electricity.
There are a number of renewable energy systems that make use of passive solar heating and this is really crucial as it cuts down the energy required for heating a home/area. For instance, from a very young age we are taught to always keep the blinds open to let the sunlight in and close them at night just before dusk and before it gets dark. This is common sense, but many people are unaware of the importance of such practices.
A renewable energy system that uses passive solar heating is one of the best methods to take advantage of the energy that is widely available from the sun and it is free. There are a lot of construction companies that good at designing low energy building, that allow your house to maximize the use of passive solar heating. In order to reduce heat demand, homes are built in such a way so that the windows let lots of sunshine in and this is especially useful during the winter. Homes should also be well insulated and windows double-glazed to keep the home warm in the winter without the need of high levels of electricity. Discuss with your local energy company and building company about what you could possibly do to build a renewable energy system that uses passive solar heating.
