Transcript of 08.04 Energy and Society
Solar power is a renewable resource. Solar power is the conversion of sunlight into electricity, either directly using photovoltaics , or indirectly using concentrated solar power.
Oil is one of the most common nonrenewable resource. During combustion, the chemical bonds in oil convert to heat, which can be used to power a variety of processes through "work."
Benefits of Oil:
Some of the advantages of oil are easily combustible, and produces high energy upon combustion helping in locomotion and in the generation of electricity and various other forms of energy. It is also widely and easily distributed all over the world. Also very large amounts of electricity can be generated in one place using oil, fairly cheaply.
Which is Better?
In my opinion, form what I have researched, I think solar power is the better option for the use of energy. It is renewable, and is overall better for our internment. Solar power can be a bit pricey, but in the long run it is well worth it. Also, oil prices are continuing to rise, therefor it could save you money to switch to solar power. I think that since technology is improving, we will see more solar powered devices in our society, and will one day become part of our everyday lives.
Disadvantages of Solar Power:
The Solar Cells and Solar Panels that are needed to harness solar energy tend to be very expensive when you first purchase them. Solar power cannot be harnessed during a storm, on a cloudy day or at night. This limits how much power can be saved for future days. Some days you may still need to rely on oil to power your home.
Benefits of Solar Power:
Solar power has come a long ways since discovered in 1998. We are now capable of putting them on houses, and even cars. A solar car gets the energy it needs to move from sunlight. If you look at the solar car below you can see that much of its surface looks black. This helps it to absorb the sunlight. Also Solar energy creates absolutely no pollution. This means that by using it, we are bettering the environment. Solar power technology is improving consistently over time, as people begin to understand all of the benefits offered by this incredible technology.

How is it used?
Solar energy can be used for day lighting, cooking, heating water or other fluids, distillation, disinfection, making saline water potable and high temperature process heating.
How is it used?
We use oil for so many different things.:
Transportation Fuels (Gasoline, Diesel, Jet Fuel)
Military and defense
Disadvantages of oil:
Some disadvantages of oil are that it is non-renewable and fast depleting. Burning it releases carbon dioxide. This can cause a lot of pollution. Mining of oil leads to irreversible damage to the adjoining environment. Oil spills as well as evaporation and fumes pollutes the environment. Used oil is difficult to recycle. The price of oil is rising,
