Petroleum  Petroleum is a liquid mixture of  complex hydrocarbon compounds formed. When marine animals and plants decompose petroleum is formed. The advantages of petroleum is that it produces a lot more energy than renewable resources. It also provides gasoline which can power are cars and it can give us fuel it also provides plastics, bubble gum, and ink. The disadvantages of petroleum it makes a lot of pollution like oil spills which can severly harm the ocean ecosystem. It can also can cause smog which can cause respiratory problems. Another disadvantage is when you burn petroleum it releases carbon doxide which is a greenhouse gas and it can lead to gloal warming.

                        HYDROELECTRIC Hydroelectric Energy is electrical energy produced by moving water.It creates electricity through  moving turbines in different  bodies of water. Not just creating electrical energy  , but hydroelectric energy does so much more and has very many advantages . First of all, Its renewable so we will always be able to get more. Another, its water powered, so it's a clean fuel source. Either no or little pollution to our environment. Though hydroelectric energy helps our community in so many ways through turbines creating electricity, they have many disadvantages . For example, all of the equipment they use in the process of creating electricity it's all very expensive. Another, they block the pathway for fish's movement through lakes, rivers, streams, and many of bodies of water.

Nuclear Energy  The definition of nuclear energy is the energy at the core of an atom.  When the atoms are split apart, this releases energy.  In nuclear energy plants they split uranium atoms inside a reactor in a process called fission. The heat from this fission is used to produce steam which spins a turbine which generates energy.      The advantages of nuclear energy include creates huge amounts of energy, it is clean energy and it reduces energy created from oil and coal.       Disadvantages include it is nonrenewable, causes large amounts of pollution, it is expensive, and there is always a chance of Catastrophe.

Solar Energy How does it work? Solar Energy is Energy received at Earth, by radiation from the sun. When the sun's rays hit solar panels, that can be placed on roofs or other places that are exposed to the sun, the panels generate the  solar energy into energy that can power buildings. Advantages of this energy source... A few advantages are that solar energy is a renewable energy source, which means it will never run out in our lifetime. Solar energy will stay renewable until the end of the world. It is constant, so we can have it as long as the suns rays are hitting the solar panels, and it can power homes. Disadvantages of this energy source... A few disadvantages are that solar panels are expensive, so they are hard to get and use. Also, If there is no light or sun, like at night time, you can't use Solar panels, because no rays are hitting the Solar Panels. You would need an alternative energy source, like geothermal energy, to have power all day, every day.

Solar energy comes from the sun as radiation received by the earth. It is used to warm buildings directly and can be converted into electricity by solar cells. Liquids warmed by the sun can be used to warm water and heat buildings. Some liquids have high holding capacity for absorbing and holding heat. Solar energy has many used such as heating houses, warming water, making electricity, and can be used for bathing. Some pollution is released from the manufacture and maintenance of the equipment. The solar heating system only works in places with lots of sunlight and the equipment is expensive.                                                                                                SOLAR ENERGY           ...

During fission, the nuclei of radioactive atoms are split into many fragments. Then a neutron hits and splits an atom, this process multiplies itself. This process releases large amounts of energy. All of this takes place inside a reactor core.                                                      Advantages Nuclear Energy makes a substantial amount of energy. It also benefits global warning and global climate change. The final advantage is that the less fu...

Biofuels

Image
Biofuels Biofuels (or biomass) is the organic matter from plants and animal wastes that contains chemical energy. This chart shows in green the amount of total renewable resources=10% and amount of biofuels=27%!!!! This is the cycle of how biofuels are created!!! DISADVANTAGES & ADVANTAGES Even though biofuels are a renewable resource, they also have some disadvantages. When biofuels burn, they produce pollution into the air. Also, biomass is very expensive and does not fuel are sources of transportation as long as oil does so many people don't use it. However, biofuels also have many advantages. Biomass can cook food, warm up our houses, and power an engine. Also, even though biofuels are created by burning plants, animal wastes, trees, and peat the plants can grow back.

Solar Energy Today solar energy is becoming very popular! People want to use this resource because it is renewable. The way these panels work is they capture the suns light and turns them into electricity. So as long as the suns shinning they produce clean energy. Advantages   Solar energy is renewable and clean this means that as long as the sun shines we have this energy source. Another good thing about the solar panels is that they do not produce pollution. Because of this they do not effect the air. Disadvantages Solar energy may work well in the day but if the sun isn't out the panels cant produce energy. Solar energy may be renewable but they take up space this can effect the wild life.

Nuclear Energy

       NUCLEAR            ENERGY Nuclear energy works in two ways. From fusion and fission. Fusion is the combining of nucleus of atoms to create energy. Fission is the nuclei of radioactive atoms that are split into two or more fragments. Two advantages of nuclear energy is that it creates large amounts of energy to use and it doesn't cause and pollution because nothing is being burned. Two disadvantages of nuclear energy is that it produces dangerous waste that remains radioactive for thousands of years. The other disadvantage is that harmful radiation can be released in the process of making nuclear energy.
