2 Energy Secutiry
2.1 Having access to affordable and reliable sources of energy
3 Hydrogen
3.1 Advantages
3.1.1 Sustainable, clean energy Readily Availible No Polutants People want to invest into it
3.2 Disadvantages
3.2.1 Need energy to collect hydrogen Not going to be benefical for years Environmental Damage Need new fueling stations
4 Advantages and Disadvantages of using resoures
4.1 Coal (Non-Renewable)
4.1.1 Advantages Produces a lot of electricity/energy Currently there is good availability of coal around the world Relatively inexpensive
4.1.2 Disadvantages It is non-renewable and fast depleting Burning coal produces carbon dioxide, a greenhouse gas

4.2.1 Advantages Carbon dioxide is absorbed when they are grown Car engines need little change to cope with bio fuels
4.2.2 Disadvantages Need a huge area of land to grow the crop, often resulting in deforestation of existing land Not completely carbon-neutral because the land has to be cleared first, then it has to be transported for use elsewhere
4.3 Wind (Renewable Resource)
4.3.1 Advantages Free Unlimited Environmentally friendly because it does not emit greenhouse gases
4.3.2 Disadvantages Inconsistent Wind turbines are an eye sore Do not produce huge amounts of electricity/energy unless it is very windy
