Prompt 1

For my first prompt i chose chapter 5 out of the book "Plan B 4.0." I chose this chapter because as I am in pursuit of a degree in the field of engineering it is very important for the future of engineering to think about environmentally friendly ways to go about anything they are doing. This can be applied to just about anything such as the production of materials, and the pollutants this may give off. Energy sources such as wind, solar, and geothermal energy is especially important because of the harm fossil fuels and coals do to our society, not to mention the fact that our fossil fuels are non renewable and our worlds supply is depleting very quickly. 

The world needs to start to move towards a more reliable and renewable energy sources and the book has depicted this very well. In the book it says that the US coast lines has so much attainable wind energy that it could power the whole country. The book also said enough light hit earth each day to power the worlds economy for a whole year. Finally the amount of geothermal energy trapped in the earth is astronomical and the first 6 miles of the earths crust contains 50,000 times more energy then all the worlds oil and gas reserves combined.
