How much of the average household consumption can renewable energy provide?
Depending upon where you live, you can choose to pay extra to have your utility provider purchase renewable energy for you. Also, depending upon your location, you already have a certain percentage of your electricity provided from renewable sources, purchased by your utility. Read up on Renewable Energy Portfolio Standards (RPS's), which differ state by state, are enacted by state legislation, and mandate that electricity providers procure a certain percentage of their electricity from renewables. Many RPS's dictate 20% by the year 2020.
Is hydro electricity reusable?
The electricity is not reusable, but as the water used in the process comes from rainfall which continues every year according to the weather, it is renewable, ie the source of the energy is constantly renewed, being driven by the solar energy which is constant.
What countries spends the most money on renewable energy and what countries spend the highest percentage of GDP on renewable energy?
The U.S. spends the most on renewable energy. By year 2013, global spending on renewable energy will hit $7 Trillion.
What renewable energy is used in the UK?
The UK already obtains about 2% of its electricity from renewable sources, chiefly from large to medium scale hydro-electric plants.
In 2005 renewable energy made up what percentage of total energy?
By production, 9.0%. By consumption, 6.2%. According to the National Energy Renewable Laboratory 2013 Databook, renewable electricity grew to nearly 15% of total installed capacity and 13% of total electricity generation in the United Statesin 2013. See pages 8 and 9 for % coal, gas, petroleum, nuclear and renewable production and consumption by year from 2000 through 2013. You can find the latest "Databook" at nrel.gov.
What is one item that is a renewable resource that does not cause pollution and does not have to be burned?
Sunlight. Enough energy from the sun lands on the earth in one day to provide the world's electricity for a year, if we caught it.
What are the advantage of using renewable?
We can use renewable energy repeatedly without depleting it.No contribution to global warming,No polluting emissionsLow cost applications when counting all costsSaving on health and its costsThe main advantage is the fact that these sources of energy are renewable. We will never run out of renewable energy (at least in our lifetime, as long as humans will exist)solar energy - the sun will always be there, and in abundance - the amount of solar energy intercepted by the Earth every minute is greater than the amount of energy the world uses in fossil fuels each year.wind energy - the wind will always exist - The energy in the winds that blow across the United States each year could produce more than 16 billion GJ of electricity - more than one and one-half times the electricity consumed in the United States in 2000.tidal energy - the moon which provides the forces that causes the tides will always be therehydroelectric energy - unless there is a drastic change in rain patterns, it will always be thereA second advantage is that we can stop using fossil fuels to generate electricity. With renewable energy we can use as much electricity as we like without adding to global warming. Renewable resources are 'green', or environmentally friendly. This is because they do not emit carbon dioxide (the biggest contributor to global warming) into the atmosphere.
What is the energy revolution?
The Energy Revolution is an effort to have the world move away from tradition 'dirty' sources of energy to cleaner, renewable energy sources. It is believed we can be at almost 100 percent renewable energy by the year 2050.
How much energy is in an lightning bolt?
If you catch on spark of a lightning bolt, it can give electricity to the world for a year.
How much can you save by changing to a energy saver rated freezer?
Energy Saver freezers can save you over fifty dollars a year in electricity.
Discuss how the Snowy Hydro scheme has effected the environment in the past and today?
The Snowy Mountains Scheme is an engineering marvel that fulfilled the vision of diverting water to farms to feed a growing nation and build hydro power stations to generate clean, renewable electricity. Each year the Snowy Scheme produces on average 4500 gigawatt hours of clean, renewable, hydro electricity, or around 70% of all renewable energy on the mainland National Electricity Market. In addition, through the use of a clean, renewable resource, generation of electricity from the Snowy Mountains Scheme displaces approximately 4,500,000 tonnes of carbon dioxide emissions every year, that could otherwise be produced by coal-burning power stations.
What are the advantages and disadvantages of using electric energy?
Renewable, or green, energy has several advantages including but not limited to the fact that it is renewable as well as the lack of harmful emissions. However, renewable energy require expensive facilities and the energy they produce is rather inconsistent. Some renewable energy types also need to be built on specific areas.
