What is is alternative energy?
Alternative energy refers to any source of energy that is different from traditional fossil fuels like coal, oil, and natural gas. Examples of alternative energy sources include solar, wind, hydropower, geothermal, and biomass. These sources are often considered more sustainable and environmentally friendly.
What is the difference between solar energy and biomass energy?
Solar energy is derived from the sun's radiation and converted into electricity using solar panels, while biomass energy is generated from organic materials like wood, crops, or agricultural waste through combustion or other processes. The key difference is the source of energy - solar energy comes from the sun, while biomass energy comes from organic matter.
What is an important renewable source of energy?
Water power, mostly in hydro-electric power plants attached to dams and rivers, is the most common source of renewable energy. Close to 17% of the world's electricity is generated from hydro.
What is one type energy source that does not use turbines?
solar power
Which best describes the energy conversion that happens when solar panels are used to make electricity?
light energy to elctrical energy
What energy is the source that panels use to make electricity?
Solar panels convert sunlight into electricity through a process called the photovoltaic effect. The energy source for solar panels is the sun, which provides a renewable and abundant source of energy.
Is solar energy a suitable source of energy for Singapore?
Yes Singapore is well placed to make good use of solar energy.
What do we need to make fire?
Fuel, oxygen, & an energy (heat) source.
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.
How do solar cars refuel?
Solar cars refuel just by regaining energy from the sun. They use all of that energy to create fuel in order to run. Some solar cars refuel by using wind energy! Solar cars gain energy from the sun or from the wind to store the energy in their fuel tanks and they use up the energy to make fuel that allows them to travel for long distances! Solar cars have no limits on how many times they can regain energy from the sun or from the wind!
Is light a renewable source of energy?
No, light is not a source of energy at all. Light is something we make with energy. We use water, wind, solar power, coal, natural gas or oil to create electricity which we use to make light.
How does solar energy work to make fuel?
There's two ways, I know one; the solar panels reflect sunlight to the top of a tower, the heat boils water to make steam and the steam spins a turbine to create energy.
How is energy related to a sun?
Because the Sun is the source of solar power, a large source of renewable energy. It also gives plants the energy they need to grow, which make it possible for all other animals to live.
How do solar cars work during the day?
Solar cars gain energy from the sun or wind to make fuel or power that have been stored in their batteries or fuel tanks. They use the power in their batteries or fuel tanks to run during the day!
Is solar power good solar power?
yes ofcourse solar power is good in many ways. some good reasons for using solar energy to power your home. 1. Cut-down electricity bill The key reason that most households convert their power source to solar energy is to cut down their electrical bill because the electrical usage generated from the sun is free. By converting as many home appliances as possible to use solar energy, you can save a significant savings in your utilities expenses. 2. It is a renewable energy source Typical electricity is generated from fossil fuel that will run out one day. Solar energy is a good alternative to replace fossil fuel as the major energy source because solar power is renewable at absolutely no cost to supply energy infinitely. 3. Environment friendly The world pollution is getting worse. Any effort that can reduce the pollution to the environment helps to save the earth. Solar panels are able to harness the energy from the sun and convert it to electricity. Therefore, the use of solar panels is environment friendly. Therefore, solar energy that is harmless to the environment will be the major energy source for future - starting today. 4. Low / no maintenance needed Once you have installed the solar power system, it can last twenty to thirty years without major maintenance needed. You may need to do system check once a year, just to make sure everything is performing as it should. Since it requires very minimum maintenance cost, your cost should be minimal.
What is the main source of the energy?
Electricity and solar radiation.well u can put turbines in sea and make them run so u get energy
What is a benefit for using alternative resources?
An alternative resource, just as the term implies is a source of something which is different from the most common source. For example the most common source of automotive fuel is fossil fuels pumped from the ground, however it is possible to make automotive fuel from corn oil or from sugar. These would be alternative resources. These will help people in the future!
