Renewable energy sources are sources of energy that can be replenished naturally, such as sunlight, wind, and water. They are best described as sustainable and environmentally friendly alternatives to fossil fuels, as they do not deplete Natural Resources and produce minimal greenhouse gas emissions.
No. It is an alternative to fossil fuels and is not exhaustible in real terms. It offers the best reduction in CO2 of anything out there, but is not a renewable.
Hydroelectric power is the cheapest renewable energy source for large-scale production. That is, it has the lowest cost to construct and maintain the generating facilities compared to the amount of energy produced. Solar power is the cheapest renewable energy source for small-scale use, such as pocket calculators, LED lights, and remote (small) electrical appliances.
That depends on where the energy comes from. Say the heat from the sun is a renewable source. Electricity fro m solar cells to a large extent is a renewable source as is wind power and wave or tidal power. If you have to use coal oil or uranium to get no.
Eduardo San Juan is a Filipino engineer who is best known for his work in renewable energy. He is credited with inventing the power from volcanic energy technology.
Solar power is considered the best energy source because it is renewable, abundant, and environmentally friendly. It harnesses energy from the sun, which is a constant and free source of power. Solar power also produces no greenhouse gas emissions, making it a clean and sustainable option for generating electricity.
Using renewable sources is more sustainable as it reduces greenhouse gas emissions, mitigates climate change, and helps to preserve natural resources for future generations. Additionally, renewable energy sources are inexhaustible and can lead to greater energy independence and security.
Renewable energy can't run out. Non-renewable energy WILL run out. Renewable energy is produced at a constant rate, non-renewable is not. Renewable energy is free when the generator is built, non-renewable is not. Renewable energy does not cause pollution (with the exception of biofuels), non-renewable energy does.
There is no single "best" form of energy as different sources have their own advantages and disadvantages. It depends on factors like availability, cost, environmental impact, and efficiency. A mix of renewable sources such as solar, wind, and hydropower is generally considered ideal for a sustainable energy future.
Probably we (mankind) will have to use a variety of energy sources, not just "one best" energy source.Probably we (mankind) will have to use a variety of energy sources, not just "one best" energy source.Probably we (mankind) will have to use a variety of energy sources, not just "one best" energy source.Probably we (mankind) will have to use a variety of energy sources, not just "one best" energy source.
solar energy and win energy are the most environment friendly because the are renewable source of energy.moreover they are present in abundance.whereas water is also a renewable source but it is more difficult to renew it.hence solar and wind energy are the best option.
We shoud use renewable energy because it helps the earth by caussing less pollution.Today were using fossill fuels which causes pollution wich is bad for earth and us everywere you go their is more fossil fuels in use then renewable energy.Thats why we should use renewable energy.

wind
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
It depends on where you are and how much wind, sun, etc. you get.
We should use them but we should use them carefully because after their gone, their gone. Also, some of them aren't good for our planet.
There isn't a one-size-fits-all solution, but solar energy is considered one of the best renewable energy sources for the future due to its abundance, scalability, and declining costs. It can be harnessed both on a small and large scale, making it a versatile option to meet a variety of energy needs.
