Renewable energy is simply derived from constantly available sources like plants, sun, wind or water. When opting for such energy, the important thing is to know if it is for domestic or commercial use so that one can put the costs into perspective. The best thing, however, is that in the long run no matter the initial cost of the project it will be still producing energy with little to no maintenance.
Top renewable energy technologies to save money
The sun is perhaps the cheapest and easiest way to get energy for domestic use, and newer technologies allow people to harness even more power. These systems come in two categories: the Photovoltaic (PV) and Concentrating Solar Panel (CSP). The CSPs are primarily used for large scale energy production as they work by having many reflectors that concentrate rays to a focal point with receivers from where electricity is produced. PVs are effective for residential homes, and the panels work by its cells absorbing photons from the rays that cause an electric field and heat can be harnessed.
For years wind energy was used for purposes of making flour, but with inventions, it was further used for producing electricity and collecting water. Since it is not economical to have wind turbines on a single home, those living in windy areas can combine and use smaller wind energy structures to produce electricity. Wind energy can further provide surplus electricity in the power grid and has also been used by power providers to give electricity to their consumers.
This is a type of energy that has been used for millenniums an example being wood. Other alternatives have been adopted over the years such as organic waste, plants or agricultural waste to produce fuels and electricity. Production of fuel, for instance, has provided a cheaper, cleaner and renewable alternative to oil based ones that cannot be replenished. These biofuels can be used to power vehicles, and they include biodiesel and ethanol. Biomass energy is a wide field, and it also covers biogas produced through anaerobic combustion, electricity produced by steam and co-firing among other biopower inventions.
For years this has been and still is the commonest form of providing energy. Due to its large scale nature and its use of water to turn turbines it is mainly used to produce massive electric power for many consumers.
The list above provides just a summary of this energy options. Solar, wind and some biomass options can be particularly cheap and efficient options for domestic power and gas production. Renewable energy also merits for its clean energy with no emissions. You can take part in saving the environment today by opting for such power while also getting a cheaper energy option.
