1. Advantages of renewable energy:The main advantage is the fact that they are renewable. We will never run out of sources of renewable energy (at least in our lifetimes, as long as humans will exist)
  • solar energy - the sun will always be there, and in abundance - the amount of solar energy intercepted by the Earth every minute is greater than the amount of energy the world uses in fossil fuels each year.
  • wind energy - the wind will always exist - The energy in the winds that blow across the United States each year could produce more than 16 billion GJ of electricity - more than one and one-half times the electricity consumed in the United States in 2000.
  • tidal energy - the moon which provides the forces that causes the tides will always be there
  • hydroelectric energy - unless there is a drastic change in rain patterns, it will always be there

On the other hand, non-renewable resources such as fossil fuels are finite - our resources of them will run out eventually.

A second advantage, renewable resources are seen as being 'green', or environmentally friendly. This is because they do not emit carbon dioxide (the biggest contributor to global warming) into the atmosphere.

Non-renewable resources such as petroleum release CO2 into the environment when they are combusted for energy. Other renewables such as biofuels are carbon neutral - producing them consumes about as much CO2 as using them produces.

2. Disadvantages of renewable energyRenewable energy is energy derived from sources that will not run out. Some of the present disadvantages are:
  • solar -- panels are expensive. Governments are not all willing to buy home generated electricity. Not all climates are suitable for solar panels.
  • wind -- turbines are expensive. Wind doesn't blow all the time, so they have to be part of a larger plan.
  • waves -- different technologies are being tried around the world. Scientists are still waiting for the killer product.
  • tides -- barrages (dams) across river mouths are expensive to build and disrupt shipping. Smaller turbines are cheaper and easier to install.
  • rivers -- Dams are expensive to build and disrupt the environment. They have also caused earthquakes. Smaller turbines are cheaper and easier to install.
  • geothermal -- Difficult to drill two or three kilometers down into the earth.
  • biofuel -- Often uses crop lands and crops (like corn) to produce the bio-alcohol. This means that more land has to be cleared to grow crops, or there is not enough food, or that food becomes more expensive.
3. Advantages of non-renewable energyThe advantage of non renewable energy, is it's easy and cheap to use. There is no better way to store transfer and use energy than gasoline for powering motor vehicles. It's quick to pump fossil fuel into a car. It's stable in the tank and a gas tank hold quite a bit, and a gasoline powered car is cheap to manufacture.
  • Coal is a ready-made fuel.
  • It is relatively cheap to mine and to convert into energy.
  • Coal supplies will last longer than oil or gas
  • Oil is a ready-made fuel.
  • Relatively cheap to mine and to convert into energy
  • It is a relatively cheap form of energy.
  • Natural Gas is a ready-made fuel. It's a slightly cleaner fuel than coal or oil, emitting less carbon dioxide.
  • Nuclear has a small amount of radioactive material produces a lot of energy. And raw materials are relatively cheap and can last quite a long time.
  • It doesn't give off atmospheric pollutants.
  • Biomass is a cheap and readily available source of energy. and If the crops are replaced, biomass can be a long-term, sustainable energy source.
  • Wood is a cheap and readily available source of energy.

If the trees are replaced, wood burning can be a long-term, sustainable energy source.

4. Disadvantages of non-renewable energyNon-renewable energy comes from fossil fuels (coal, oil, natural gas, uranium):
  • they are non-renewable and fast depleting;
  • they leave behind harmful by-products upon combustion, thereby causing a lot of pollution;
  • mining of such fuels leads to irreversible damage to the adjoining environment;
  • Fossil fuels pollute the environment
  • They will eventually run out.
  • Prices for fossil fuels are rising, especially if the real cost of their carbon is included.
  • Burning fossil fuels produces carbon dioxide, a major cause of global warming.

Renewable resources are environmentally-friendly as they do not require the burning of fossil fuels, which releases carbon dioxide. Renewable resources will never run out unlike fossil fuels, so we would not need to conserve energy in the future.

However, renewable resources rely on the environment. If there is no sunlight or wind, energy cannot be produced. Lots of money have been put into research, technology and building of the gadgets, making it extremely expensive and unaffordable for a few poor countries.

One of pros of using renewable energy sources is that they are environmentally friendly. They are sustainable for the long term future. One of the cons is a lack of infrastructure. in addition, the initial cost is high.

Fossil Fuel

Pros: Lots of energy from a small amount

Cons: It may soon run out, causes pollution, expensive

Renewable Energy

Pros: It will never run out (unless the world blows up), no pollution

Cons: Costs a lot of money to make solar panels, turbines etc., doesn't produce as much energy

Advantage of renewable enegy are: (1) it has a long lifespam, i.e it can last for a long period of time. (2) it can be rechargeable unlike the non-renewable ones.

Renewable energy has less of a negative impact on the environment. However, renewable energy can be costly to initially develop and implement.
