Non Renewable Sources

A non renewable energy source is one which is finite and will eventually run out.

The main 3 non renewable sources are coal, oil and natural gas. All these sources are extracted from the earth which requires energy which probably comes from non renewable sources. All 3 sources are transformed into energy by burning them. When burnt they release gases which are used to turn a turbine which basically rotates a magnet inside a coil of wire, inducing an electric current.

These gases may be useful by spinning a turbine however the gases are very harmful to the atmosphere. The most harmful gas released is carbon dioxide which causes the greenhouse effect and therefore climate change. Another problem is that these sources will eventually run out, and if the world is not prepared we could see mass panic and even extinction of the human race.

My advice is to invest in clean, renewable energy sources and to become self sufficient. Oil prices are going to increase exponentially as reserves decrease. Buy wind turbines and solar panels to be prepared for what is to come. An investment today can benefit you more than it first appears.

Climate Change

Here i will give a brief beginner's description of climate change.

At the start of the industrial revolution we began to require energy to power machines and the easiest way to do this was by burning fossil fuels. The consequences of this were not realised until some years later.

When fossil fuels such as coal, oil and gas are burnt they release carbon dioxide into the atmosphere. The suns light can penetrate this layer of carbon dioxide as UV rays which in turn warm up the surface of the earth. This infrared heat however cannot escape back out of the atmosphere causing the greenhouse effect. With this heat being trapped continuously over a long time, the average temperatures across the globe start to increase (climate change).

This causes a whole host of problems such as melting of the ice caps, which cause sea levels to rise, which means some countries will be flooded. It forces animals out of their natural habitats and can lead some to extinction having knock on effects on whole ecosystems, including us as we are at the top of the global ecosystem and therefore the most affected.
