Renewable Resources (ERR)
Energy from Renewable Resources (ERR) refers to the energy sources which can be renewed indefinitely without depleting their supply. A renewable source, also called a non-renewable resource, is an energy source that will continually replenish itself to replenish the fraction depleted by use and generation, either via natural replenishment or other naturally recurring processes within a finite quantity of time at a human level. The most commonly used of these energy sources are the sources of fossil fuels like oil, gas, and coal. There are many different methods for using renewable energy. They include wind turbines, solar panels, geothermal systems and hydropower systems.
Among the most popular types of renewable energy sources are solar energy sources and wind power. Both of these systems have a wide range of advantages. With solar energy sources, for example, it is possible to capture the heat of the sun and pump this heat into running water through a turbine. As well as being capable of heating a home, the heat is stored in the system’s pipes, which can then be used for domestic purposes.
the main disadvantages
There are a variety of advantages inherent in both types of renewable energy sources, but with hydro and wind energy, especially hydro energy, there are certain disadvantages as well. One of the main disadvantages with using both solar and wind power is the large amounts of energy that would have to be expended in order to create a practical amount of output. Also, both of these systems require an external power source in order to function, and if the power source goes down, so does the ability to generate or utilize the stored energy.
One advantage inherent in both types of renewable energy sources is that they are self-sufficient. Unlike nonrenewable sources like coal and petroleum, when these systems are used, they do not need to be connected to any external power source in order to work. They also will not cause a significant increase in your monthly electricity bill. You will be able to use as much of your power as you need without having to worry about whether or not the sun or the wind is blowing.
renewable energy facilities
One important consideration when considering which renewable energy facilities are the most cost-effective is their level of dependence on external power sources. The better the dependency, the more costly the facility will be over time. The two types of systems that are extremely cost-effective are solar power and wind energy facilities. In general, the more dependence there is on an outside power source the more expensive the generator is likely to be.
In summary, while there is an ongoing debate over which technologies are the most effective at creating a cleaner, greener world, the best way to determine which renewable resources are the most cost-effective, as well as the most reliable, are your own personal needs and your level of knowledge and experience. Some of the best ways to determine this is by doing your own research. There is a wealth of information on renewable technologies, and some even offer online calculators to help determine how much it would cost to generate certain technologies over a given period of time. For example, there are a number of good online energy generation calculators available. You can also find comprehensive and very well written books that can explain in detail how different renewable technologies work, including both their benefit and drawback.
