(URGENT)
1. What is renewable energy?
2. How is renewable energy different from conventional source?
3. Can renewable energy resource replace Fossil Fuels?
4. How does this alternative energy source impact our environment?
5. Will this alternative energy source stop global warming?
6. If you are using solar energy for producing electricity and one fine day the sun is not shining,will you still get electricity, What do you think?
Answers
1. energy from a source that is not depleted when used, such as wind or solar power.
2.Regular” or “Conventional” energy is generated from fossil fuels, including coal, oil, and natural gas. “Green” or “Renewable” energy is generated from sources like the sun, wind, and water.
3.Renewables can effectively replace fossil fuels, creating crucial environmental, social and economic benefits. Global dependence on oil, natural gas and coal–and the damage this dependence inflicts–is well documented. But a transition away from fossil fuels is in progress and simply needs to be expedited.
4. Renewable energy sources such as solar and wind don't emit carbon dioxide and other greenhouse gases that contribute to global warming. ... As greenhouse gases trap heat in the atmosphere that would otherwise escape into space, average temperatures on the surface are rising.
5.A solar photovoltaic (PV) system changes sunlight into electricity. Sunlight is caught by the solar panels and converted into usable electricity by the inverter. This can then be used to power appliances in your home directly, or stored in a battery for use later when the sun is not shining.
Answer:
1_energy from a source that is not depleted when used, such as wind or solar power.
2_ Conventional energy sources such as natural gas, oil, coal, or nuclear are finite but still hold the majority of the energy market. However, renewable energy sources like wind, fuel cells, solar, biogas/biomass, tidal, geothermal, etc. ... Wind power is a clean, emissions-free power generation technology.
3_The short answer: yes. Renewables can effectively replace fossil fuels, creating crucial environmental, social and economic benefits. ... Global dependence on oil, natural gas and coal–and the damage this dependence inflicts–is well documented.
4_ Electricity from renewable energy sources produces between 90-99% less greenhouse gases (GHGs) compared with coal-fired plants and causes 70-90% less pollution. ... Focusing on renewable energy sources other than fossil fuels and coals might help in avoiding environmental impacts, specifically from air pollution and GHGs.
5_ Renewable power could cover up to four-fifths of global electricity supply by 2050 – drastically reducing carbon emissions and helping to mitigate climate change. However, strategies are needed to fully integrate the variable renewables, solar and wind energy.
6_ Solar panels require sunlight to generate electricity for your home so they do not work in darkness. Thus – the simple answer to this question is no. ... The purpose of a solar panel system is to absorb sunlight, also know as photovoltaic energy (PV), and convert it to direct current (DC) power.
