Understanding the Problem

The availability of non renewable sources is decreasing with time and the damage is increasing. Fossil fuels are the main source of energy and all of which are non renewable. They provide 80% of global energy use and the demand is growing at a rate of about 2% per year. Fossil fuels emit carbon dioxide into the atmosphere and in the last 150 years its concentration has grown 28%. (See graph)






Our global commercial energy consumption is now over 10 GIGA TONES OF OIL, which is roughly equivalent to the work capacity of 20 human slaves for every person on the planet.



The main problems of using non renewable sources:

• With time it is going to run out, in the near future as we use so much and it's still increasing!
• The emissions of fossil fuels are overwhelming our ecosystems capacity to absorb them, causing greenhouse gases in our atmosphere. This then leads to climate change.
• Negatively impacting the out living enviroment. The total amount of energy use is so great that it has the potential to disrupt global ecosystems.
