Will the use of renewable energy help to manage climate change and difference between energy conversion and energy conservation?
Climate changes is the result of an exaggerated use of fossil energy sources such as coal, oil and gas. Therefore, both energy conservation policy and replacement of fossile energy sources by renewable ones are paramount to manage the climate change.
Note that renewable energy sources all come from the conversion of solar radiation.
Renewable energy produces zero waste. There are no carbon emissions of greenhouse gases that contribute to climate change or air pollution. It is, thus, one of the best choices for countries combating the climate change problem. Renewable energy sources used in energy generation helps to reduce greenhouse gases which mitigate climate change reduce environmental and health complications associated with pollutants from fossil fuel sources of energy. Renewable energy comes from the Earth's natural resources sunlight, wind, waves, the tides and geothermal heat from deep within our planet. It has two great advantages: it will never run out, unlike oil, coal and gas. It’s clean it doesn't pollute the planet or cause dangerous climate change. Energy transfer is the movement of energy from one location to another. Energy transformation is the changing of energy from one type of energy to another. Energy conservation means that the total amount of energy always remains the same. Switching to clean sources of energy, such as wind and solar, thus helps address not only climate change but also air pollution and health. Look carefully at the words “conservation” and “conversion”. In general, the first means to keep something the way it is, the latter means to change it. Energy efficiency generally pertains to the technical performance of energy conversion and consuming devices and building materials. Energy conservation generally includes actions to reduce the amount of energy end use. Reduction in energy use by doing modification in equipment, set points, procedure e.g. Reduction of operating time, using VFD etc and there is cost associated with energy conservation, management refers to effective use so that cost benefit balance is achieved. Generating electricity and heat by burning fossil fuels coal, oil, or gas causes a large chunk of the greenhouse gases, such as carbon dioxide and nitrous oxide that blanket the Earth and trap the sun's heat.
