AnswersDriveWhile in use, solar panels create absolutely no waste or emissions. Unlike fossil fuel power plants, they produce clean, renewable energy from a fuel source that requires no locating, excavation, transportation, or combustion. It's a simpler, cheaper, cleaner, and all-around better energy solution.
1
Why is solar power a renewable energy source?
Solar energy is a renewable free source of energy that is sustainable and totally inexhaustible, unlike fossil fuels that are finite. It is also a non-polluting source of energy and it does not emit any greenhouse gases when producing electricity.
2
How much energy is produced by solar panels?
Using 4 hours of full sun, gives you this equation: 250 watts x 4 hours. That's 1 kWh (1,000 watts) in a day per 250-watt panel. If you multiply 1kWh per panel by 30 days in a month, you'll find that each 250 watt rated panel will produce about 30 kWh in an average month.

Why do we need to use solar energy?
Unlike conventional power, solar produces no harmful emissions that hurt the environment. It's a clean, renewable process that uses the most natural of all resources: the sun. Even the energy used to produce the PV cells is paid back soon after.
4
Why solar energy is the best energy source?
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. 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.
5
Is coal the cheapest form of energy?
Cheapest source of energy. It is by far cheaper than nuclear, natural gas, oil. Unlike other forms of energy (nuclear, natural gas, oil, hydroelectric), coal provides many jobs in removing coal from the earth, transporting it to the utility, burning it, and properly disposing of coal ash. Coal is American made.
6
What are the benefits of using wind energy?
Advantages of Wind Power. It's a clean fuel source. Wind energy doesn't pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural gas.
7
How much money is spent on fossil fuels?
The costs of continuing on our current energy path are steep. American consumers and businesses already spend roughly $700 billion to $1 trillion each year on coal, oil and natural gas, and suffer the incalculable costs of pollution from fossil fuels through damage to our health and environment.
8
What are the bad things about solar energy?
Bad Things About Solar Panels. Solar power harnesses energy from the sun and transforms it into energy that can be used by consumers. One of the most common ways this power is harnessed is solar panels, also known as photovoltaic panels. Unfortunately, there are some disadvantages to the panel system.
9
Is Fossil fuel a biomass energy?
Fossil fuels release carbon dioxide into the atmosphere. Coal has the approximate chemical formula CH. Natural gas is the best fossil fuel in terms of energy output per unit carbon dioxide emitted. Biomass is renewable because a new crop can be grown after each harvest, and biomass is a low carbon fuel.
10
Is charcoal is a fossil fuel?
The methane and carbon monoxide released during charcoal production have short atmospheric lifetimes compared with that of fossil fuel carbon dioxide. In the long run, the net effect of charcoal on the climate is nil because the wood used to produce charcoal was formed from carbon dioxide by photosynthesis.
11
Is geothermal energy a fossil fuel?
There are many advantages of geothermal energy. It can be extracted without burning a fossil fuel such as coal, gas, or oil. Geothermal fields produce only about one-sixth of the carbon dioxide that a relatively clean natural-gas-fueled power plant produces. Binary plants release essentially no emissions.
12
How efficient is burning fossil fuels?
Efficiencies. Taking into consideration the three conversion processes, thermal, mechanical and electrical, used to extract the energy from fossil fuels the overall efficiency of a modern fossil fuelled electrical power generating plant will be about 40%. This means that 60% of the energy input to the system is wasted.
13
How do we acquire coal?
We obtain coal from underground seams. A seam is a layer of ore or coal that is thick enough to be profitably mined. We obtain the coal in one of two ways: By surface mining, which involves removing the soil and rock above the coal seam so that it can be removed from the surface.
14
Can renewable energy replace fossil fuels?
Most analysts think that the world's demand for energy will keep growing in the near future. But they also believe that as time passes, renewable sources of energy — hydroelectric, biomass and perhaps nuclear energy, but above all wind and solar — will replace fossil fuels, reducing carbon emissions.
15
How is burning fossil fuels bad for the environment?
Air pollution. Burning fossil fuels emits a number of air pollutants that are harmful to both the environment and public health. Acid rain is formed when sulfur dioxide and nitrogen oxides mix with water, oxygen, and other chemicals in the atmosphere, leading to rain and other precipitation that is mildly acidic.
16
Is hydropower a fossil fuel?
Hydropower is fueled by water, so it's a clean fuel source, meaning it won't pollute the air like power plants that burn fossil fuels, such as coal or natural gas. Hydroelectric power is a domestic source of energy, allowing each state to produce their own energy without being reliant on international fuel sources.
17
What do we use to collect solar energy?
Solar power is arguably the cleanest, most reliable form of renewable energy available, and it can be used in several forms to help power your home or business. Solar-powered photovoltaic (PV) panels convert the sun's rays into electricity by exciting electrons in silicon cells using the photons of light from the sun.
18
How much does it cost to install solar panels?
On average the total cost of solar installation can be between $15,000 to $29,000 for average sized systems sized between 4kW and 8kW. Sunrun solar lets you get started for as little as $0 down and helps you lower your electric bill. If you want to own your system, we do that too.
19
How are oil and coal forms of solar energy?
Coal and oil are indirect forms of solar energy, the end result of what happens when you apply gigantic geological forces to now dead photosynthetic plants over the course of millions of years. Biomass is effectively coal in a hurry: the plants absorb sunlight to grow and we chop the plants down and burn them.
