• BioFuels
• Solar Energy
TASK – Exercise Book Image you live in a country with an estimated amount of
oil left for 50 years. Once this runs out that is it!Which of the 3 options below will you choose to present
to your cabinet as the best way forward;1) Invest in alternative forms of energy for your
country, i.e. build more wind farms, more HEP, etc. 2) Buy resources from abroad, there are plenty of other
countries that have lots of resources that are willing to sell and export the oil to you. Then in 50 years time you will have loads of oil and other countries will start to run out and come to you for oil.
3) Do nothing and just wait and see what happens; besides you won’t be running the country when it all runs out!
