Energy Sources

Renewable energy sources are being used all over the world. Brilliant minds have devoted their lives to finding resources that do not leek greenhouse gases into the ozone, or cost large amounts of money. In the Video "New Energy Revolution," it shows some of the renewable energy sources being used all over the world. For example, wind energy, solar power, Hybrid cars and using methane gas for stove fuel. These are all excellent examples of renewable energy as they are all affordable and convenient as well as being efficient. The question is, will people use them, or stay with the atmosphere damaging fossil fuels of today?

Solar power is an excellent energy resource. The sun gives us free rays, so why not use them as a power source. The video shows Japan as a country which is educating their people about the risks of keeping the current resources and providing information on renewable energy sources, like solar power. Solar power is set out in a row of panels which take in the suns energy and provides power for homes and other things. Cars can now be solely power by solar panels, creating huge possibilities. If solar energy was used world wide, along with other renewable sources, the world would be cleaner and more pleasurable to live in, knowing that the greenhouse gases are under control.

Hybrid cars are cars that run on electricity (charged) and some gas. The Hybrid car was invented to cut down the hazardous gases that are emitted by normal cars. The Hybrid car emits 90% less greenhouse gases than the normal car and inventors want to make it 100%, meaning no gases emitted. Toyota is leading the pack in terms of producing a usable, affordable Hybrid car. The car is charged at places similar to petrol stations with an electric charger that easily plugs into the front of the car. This marvellous invention only runs on gas, when it is doing speeds of 100 kilometres per hour or more. Meaning that the Toyota car is excellent for city use, where only medium speeds are reached. If more people were to invest in Hybrid cars, there would be less pollution than if they stuck with the normal cars of today.

In Vietnam, cow and pig manure and waste, is washed into a drain, where the gas is allowed to gather through pipes, then leak into a large 'bag,' which is situated above the stove. The Methane (the gas produced by the cow and pig manure), is then stored there and when ever they want to light the stove, the bag is tightened by adjusting a belt, and the gas is lit, flaming the stove. This procedure is very environmentally friendly as there is no need to extract it; it is just there, near the animal's deposits. Of course this way of using renewable energy resources is not useful for people living in big city buildings, or suburbia, as they have no animals to get it from, but it is an excellent example of using your mind to think of a practical way to use natural things that will cause no destruction to the environment or the ozone layer. By thinking of ways to provide our material world with energy, we will help the world become a better place to live.

Wind is a natural occurrence, where air is pushed in a direction powerfully or gently. In
