Alternative energy sources
There is an excellent website called Daily Infographic which produces wonderful visual material about many different topics.
Have a look at it, then answer the following questions:

1) What is the goal for limiting global warming?
2) How much energy is produced by solar power?
3) What is the average size of a wind turbine?
4) How much of Iceland's heating is geothermal?
5) What are the problems with using hydrogen as an energy source?

Bonus question (this is just for you!) - how much of your countries energy comes from alternative sources? Please let me know the answer in the comments section.
