The role of the renewable materials is very important to human beings especially to climate change because, renewable energy utilizes Natural Resources such as sunlight, wind, tides and geothermal heat, which are naturally replenished.
Non-renewable sources of energy, like coal, oil and natural gas, emit carbon dioxide, a greenhouse gas that is contributing to climate change. This is why we need to move to renewable sources.
Renewable energy technologies range from solar power, wind power, and hydroelectricity to biomass and biofuels for transportation.
Climate change refers to the variation in the Earth's global climate or in regional climates over time. It describes changes in the variability or average state of the atmosphere over time scales ranging from decades to millions of years. These changes can be caused by processes internal to the Earth, external forces or, more recently, human activities. . The external factors that can shape climate are often called climate forcing and include such processes as variations in solar radiation, the Earth's orbit, and greenhouse gas concentrations.
About 13 percent of primary energy comes from renewables, with most of this coming from traditional biomass like wood-burning. Hydropower is the next largest source, providing 2-3%, and modern technologies like geothermal, wind, solar, and marine energy together produce less than 1% of total world energy demand. The technical potential for their use is very large, exceeding all other readily available sources.

∙ 12y agoRenewable energy has a role only in reducing climate change. In a world powered by renewable energy the greenhouse gases in the atmosphere would slowly return to their normal levels, and the dangers from global warming would disappear.
Energy use from fossil fuel is the dominant source of greenhouse gas emissions made by man. Burning fossil fuels to generate electricity releases additional carbon dioxide which the carbon cycle is unable to deal with. If we could produce all our energy from renewable sources tomorrow we would have very little problem with climate change.
Renewable energy includes hydroelectric power, tidal power, wind, solar, geothermal and biomass. These are not depleted when we use them. If I put a solar panel on my roof, that will not make it less sunny tomorrow. Renewable energy does not cause carbon dioxide emissions, and therefore does not contribute to climate change, like burning fossil fuels does. (Actually, nuclear power is non-renewable, but does not contribute to climate change.)
It is true that no single technology can provide all the power we need, but by combining different technologies (for example: Solar and hydrogen fuel cells, which could store energy from the solar panels for when the sun does not shine), it will be possible to provide base load power from renewable sources.

What is the potential role of marketing in tackling the challenge of climate change?
This is to Sell People on the Idea of Non-Consumption.
What can journalists do to mitigate climate change?
Journalists have a role in mitigating climate change through their work, which is to report the news.So journalists will:Report on significant climate scientific announcements, using Plain English where appropriate, so their readers can understand.Recognise that it is not appropriate to "balance" this story by giving space to the views of a non-expert who is not a climate scientist.
What is man's role in global warming?
Humans are responsible for serious deforestation as well as the burning of fossil fuels (coal, oil and natural gas). Climate scientists agree that this is what is causing global warming and climate change.
What is the role of energy in physical and chemical changes?
Energy can be absorbed or released in a chemical or physical change, it is not destroyed or created. It simply assumes a different form. This is the law of conservation of energy. Accounting for all the energy present before and after a change is not a simple process. But scientists who have done such experimentation are confident that the total amount of energy remains the same.
How has the climate of Georgia played role in Georgias growth and development?
by water conservation and northern mountains.
How renewable energy can protect the nature?
energy plays a vital role in itself and our nature is somewhat dependent in it. Thus, renewable energy can protect the nature.
What describes the role of an electromagnet in a generator?
Its role is to change mechanical energy into electrical energy.
What are aerosols and what role can they play in climate change?
Aerosols are chemicals such as aluminum and barium. They can play a role in climate change by being sprayed from aircraft into the atmosphere in order to cause a desired result.
What best describes the role of an electromagnet in a generator?
Its role is to change mechanical energy into electrical energy.

How do veld fires cause climate change?
The fires are producing huge amounts of carbon dioxide, a gas that plays a major role in exacerbating global warming and climate change. The veld fires are usually caused by man.

How role does climate play in the economy of the Arabian gulf location?
Climate plays a major role in life in the gulf.
What is the role of energy in sublimation?
Any change of state (a.k.a. change of phase) involves a transfer of energy. The case of sublimation is similar to the evaporation of liquids: you have to input energy to turn the solid into a gas; you get energy back if the process occurs in the opposite direction (from gas to solid).
What is man's role in global warming?
Humans are responsible for serious deforestation as well as the burning of fossil fuels (coal, oil and natural gas). Climate scientists agree that this is what is causing global warming and climate change.
Why is energy of the sun renewable?
The sun is our most powerful source of energy. Sunlight, or solar energy, can be used for heating, lighting and cooling homes and other buildings, generating electricity, water heating, and a variety of industrial processes. Most forms of renewable energy come either directly or indirectly from the sun. For example, heat from the sun causes the wind to blow, contributes to the growth of trees and other plants that are used for biomass energy, and plays an essential role in the cycle of evaporation and precipitation that makes hydropower possible.
