How does renewable energy save money?
Energy is not renewable. The sources to make that energy may be. After the initial cost of plant and equipment some sources are practically free so the only costs are maintenance costs..
Why solar energy is harnessed?
Solar energy is harnessed because it is a renewable source of energy and we should make full use of it to lower the pressure on the traditional or non-renewable sources of energy.
What are positives about using renewable energy sources?
it is renewable and it is available throught the world
Are most energy sources renewable or nonrenewable?
Most energy sources are non-renewable, like coal, oil and natural gas, which are all burned to produce electricity or to power vehicles. They don't renew when we use them up.Our renewable sources (Solar, Wind, Water and Geothermal power) make electricity and they still come back tomorrow. We are only beginning to use these sources.
Is a windmills a nonrenewable resources or a renewable sources?
It would be naïve to say that there is a completely renewable source of energy. The sun, for example, which is the source of all energy on Earth, will form a Red Giant in a few billion years time, and will produce far less energy than it had in the past. Additionally, although wind (which relies on the sun) is renewable per say, machines to make use of wind energy, such as wind turbines, require maintenance et cetera and are in that sense, not *completely* renewable. However, for our purposes, and especially in contrast to Fossil fuels, the Sun, the wind, the tides et cetera are renewable sources of energy. Windmills are machines which convert the wind's energy into another form of energy. They, themselves, are not "renewable *sources," rather they can make use of a 'renewable' source, 'the wind,' to transform kinetic into potential energy.
Where does nuclear energy come from to make renewable energy work?
Nuclear energy and renewable energy are not related. Renewable energy does not use nuclear energy.
Why is it important that you increase the use of energy from renewable sources?
Because when you depend on energy sources which are not renewable and they run out, you are (for lack of a better descriptive and effective term) screwed. However, dependence on renewable sources means you will hypothetically never run out of energy and renewable sources are typically cheap; the only cost is the initial setup and maintenance.
What is arenwable energy source?
A renewable energy source is one that is being renewed on a regular and constant basis, such as the wind, geothermal, tides, and sunlight. It takes a very long time and a lot of effort to make oil, coal and gas so they are not considered renewable sources of energy.
What is solar renewable energy?
Renewable energy is an energy source that is either in relatively limitless supply, or that quickly regenerates when consumed.So solar, wind and water power are kinds of renewable energy, because they keep coming back even after we've used them.Coal and oil are NON renewable sources of energy, because when they're gone, they're gone.Renewable energy is found in abundance and we must make use of these resources such as solar, wind, hydropower, geothermal to the best advantage. For instance wind energy must be tapped to generate electricity.Renewable energy is any source of energy which can be used or consumed without going into the state of being unusable. Examples of nonrenewable energy sources would be petroleum, natural gas, coal, etc. You will find that everyday fossil fuels are nonrenewable sources of energy. Some examples of renewable energy would be; solar energy, hydro energy, heat energy, heat from friction, etc."A source of energy that is not expected to deplete through constant use or can be replaced or grown within a relatively short period of time."The definition of renewable energy is a resource that you can take and give back,(ex. trees, plants, animals, vegetables.By the name itself it has the definition involved i.e., the source of energy that is renewable is called as the renewable energy.... this is other wise called as the non conventional energy because we have replaced the conventional sources of energy ( like coal, oil, fossilfuel etc.,) to the non conventional source of energy( like solar, wind, hydro, geothermal, tidal, wave, peizo, mhd's etc.,)Energy, of itsself, is never renewable. It always degrades towards hbeing low level heat (entropy). There are however renewable energy sources. In general, renewable energy is identified as the energy that comes from sources that can be replenished or those that cannot be depleted. Such sources include wind, rain, tides, sunlight, waves and geothermal energy.Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat
Why don't we use a lot of renewable energy now?
Because renewable energy use does not make for good consumers.
What are the 2 advantages of classifying energy sources as renewable and non- renewable?
advantages of renewable- it can be used over and over again. used to make power disadvantages of renewable- solar panels are expensive, so are wind turbines advantages of non-renewable- very efficient. lots of experience in field disadvantages of non-renewable- it pollutes the environment. it is difficult to dispose of
The earth most important nonrenewable energy source is?
Non-renewable energy sources are those that drain the fossil reserves. The most important non-renewable energy source on Earth is coal. If something is not done to make the switch to clean or green energy, the coal supply is not expected to last for more than 40 to 50 years.
