Different fossil fuels such as oil and natural gas, renewable energy is stable because it is derived from endless sources such as the sun (solar), wind, biomass, water (hydro) and geothermal. Renewable energy sources are not human made and occur naturally.
Alternative Energy Sources
Because of their stability, renewable energy sources can be counted upon for producing long term, cost effectual and efficient energy. Also known as ‘green energy’, these environment friendly energy sources are generally non-polluting and cleaner to use than fossil fuels such as oil. There are even some new products that utilize renewable energy, such as this Powertraveller Solargorilla review. When generally used in systems to generate electricity, they do not emit off toxic waste or produce greenhouse gases.
At the level of our current electricity producing technology, the basic alternative energy sources are solar, wind, hydroelectric and hybrid systems.
Solar power is made from sunlight, in the case of electricity generation or, in the case of solar hot water systems, the heat from the sun. For an example, see this Solio Magnesium solar charger review. Solar panels are comonly mounted on the roof to allow an unhindered path for the sun’s power. Solar hot water systems are very effective and have been used for many years while solar electricity is a reasonably new technology. Solar electricity is generated by photovoltaic cells contained in the solar panel. The cells produce an electric voltage when sunlight falls on them.
Wind power uses the force of the wind to drive a wind turbine which generates electricity in the customary way. Exactly like a general windmill, the water pump is replaced by an electric generator. Wind generators utilize a completely natural phenomenon to generate green renewable clean energy.
Hydroelectric electricity is electricity produced by the force of water flowing over and driving a water turbine or generator. Instead of wind as in a wind turbine, the flowing water rotates the turbine’s blades. Like wind turbines, the efficiency of hydroelectric systems is dependent on the capability of a good supply of flowing water. There are micro-hydroelectric systems accessible which can be used in remote areas where there is a good water supply.
Hybrid power supply systems are simply a combination of the already mentioned energy sources. Customarily consisting of solar panels and wind turbines, these can also integrate more usual generating equipment such as diesel generators and battery banks. The current technology for these systems is already quite mature and well tested. Because of the flexibility offered by hybrid systems, these are comparatively easy to upgrade or expand as required.
When it comes to performing an option green energy system, there are many possibilities ranging from the complete professional system costing many thousands of dollars up front to the basic system which starts off small and can be expanded when more funds are available.
In the years to come, we will hear more and more about green energy and as the power bills continue to increase, the cost of going green will begin to look very adorable.
