The renewable energy resource is abundant, as well as that the innovations for collecting it and converting it into useful energy, are getting better rapidly. There are many methods to use renewable energy. The majority of us already make use of one or more renewable resource in our daily lives every day.
Renewable Energy Resource List – 10 Renewable Energy Resources
The following is a list of the majority of these energy sources:
- solar – from the suns rays directly
- wind – from weather patterns/ wind induced by the sun’s rays
- hydro – from water, its velocity and from its height/ making use of gravitational energy in stored water etc.
- tidal – sea currents, and differences in relative elevation of water caused by high tidal ranges seen in estuaries etc a sub category of hydro-power
- biofuel– from the chemical processing of organic materials (i.e. not fossil fuels)
- biomass – combustion (burning) of organic materials
- geothermal – using either geological heat from the earth’s core, or the flywheel effect where shallow rocks retain summer warmth throughout winter below-ground in boreholes
- household trash or waste – by incineration or more sophisticated methods such as anaerobic digestion
- food waste – the food discarded by householders via the anaerobic digestion process and biogas
- landfill gas – generated by natural decomposition in landfills, and collected and combusted to provide biogas.
When Renewable May Become Just “Greenwash” – Problems with Renewables
Renewable renewable energy resources such as burning biomass are occasionally considered to be “carbon neutral” alternative to fossil fuels. However, not all renewable energy sources are as “green” as they may appear at first. Care must be taken to avoid renewable energy sources that need a lot of fossil fuel consumption in the background in order to make them.
Renewables are not inherently alternate power sources for this purpose. For instance, the Netherlands, as soon as leader in operation of palm oil as a biofuel, at one time put on-hold all aids for palm oil as a result of the scientific evidence that their usage “may in some cases incur even more ecological harm than fossil fuels”.
Environmental teams working for the Netherlands federal government traced the beginnings of imported palm oil and found a lot of embedded fossil fuel use. As a result they decided to license which of the operations which create the oil, that were found to be doing it in a responsible manner.
Another problem with renewable energy sources which turned out to be less than “green”, and not very sustainable occurred ten years ago when regarding bio-fuels made from food cops. The realization suddenly dawned on the governments which were subsidizing this type of energy production that it would never be truly viable. They realized that even transforming the whole grain produce of the United States would be massively inadequate as a method to solve fossil fuel dependency, and it was pushing up the cost of food, because fuel demand was beginning to compete with food production.
How Subsidizing Biofuels from Food Crops Turned Out to be a Failed Concept
Data from fuel production from food crops showed that just 16 % of its automobile energy needs, as well as the complete annihilation of Brazil’s CO2 absorbing rain forest to make way for biofuel production has made it clear that placing energy markets in competition with grocery store leads to greater food rates. Not only that, also insignificant or negative influence was being witnessed on energy issues such as global warming. Plus dependence on international energy supplies was not reducing substantially either due to this policy, although it was hoped for.
“So, that’s how renewables can go wrong… What is the true meaning of ‘renewable’ when used correctly then?”
Renewable energy uses energy resources that are consistently capable of refilling themselves naturally, the sunlight, the wind, the water flow, the planet’s warmth, as well as plants, all do this. The best renewable energy technologies turn these energies into highly usable types of energy efficiently and these can be power, but likewise can be heat, chemicals, or mechanical movement power.
Renewable energy resource consist for example, of the wind. Some days it blows a soft breeze. Various other days it can be very harsh. A house wind energy generator could be positioned to collect this sort of energy. Some of the mini-turbines sold to do this are extremely tiny, consequently, they are suitable to be put in your own yard. Others are substantially larger and are made for the open fields, where strategically placed, they will be in the windiest spots.
Renewable Energy is energy stemmed from sources that are inherently regenerative, or for all functional purposes can not be diminished. Sources such as the sunlight as well as the wind, can never ever be worn down and therefore are called renewable. They create less exhausts as well as are readily available locally. Their use can, to a huge degree, by reducing demand for the dirtier old fashioned coal and oil based sources, reduce chemical, and radioactive as well as thermal pollution.
They are a practical source of clean and also infinite energy. These are the non-traditional sources of energy that will need to power the earth for all future time, if the earth is to survive as a planet that is habitable as we know it!
Renewable energy in the United States
Renewable energy in the United States made up 19 percent of the locally generated power in 2013, and also 12 percent of total energy generation. As of 2014, greater than 143,000 people operate in the solar industry as well as 43 states deploy net metering, where energy utilities buy back excess power created by solar selections.
Renewable resource in the United States has made big strides by expanding its capacity very rapidly, and is up 187 percent of the domestically generated electrical power in 2011/2/3 California is a leading state, which others follow. Additionally, around 20 percent of California’s electrical energy originates from what are known as RPS eligible renewable sources.
“What Needs to happen to Renewable Energy in the Near Future?”
Renewable resource resources are already existing over vast geographical locations, as opposed to various other energy sources, which are so far concentrated in a minimal number of countries. This needs expanding to all countries.
Quick deployment of renewable energy and also energy effectiveness is resulting in significant energy safety improvements, climate adjustment mitigation is therefore being achieved although not as fast as it needs to be. Despite the large investments needed, part of which is being burdened on the taxpayer/ and house owners, there are economic advantages.
Is there Public Support for Renewable Energy?
In international public opinion studies there is solid support from the “man/woman in the street” for subsidizing renewable sources such as solar energy and wind power. At the nationwide level, at the very least 30 nations worldwide currently have adopted a positive policy toward encouraging renewable resources, with targets to soon be adding more than 20 percent of renewable sourced energy supply.
National renewable resource markets are projected to continue to grow strongly in the coming decade and also beyond, but your support is needed to ensure that this momentum toward the transfer of the world’s use to renewable energy, is maintained.
