Humanity's Energy Needs: Humankind's total annual energy need is approximately 4 x 10^20 J.
a) What is this in Watts?
b) The solar energy reaching the Earth is ~340 W/m^2. If we could collect 100% of the energy hitting 1/20th (5%) of the Earth's surface, and Earth's surface is 5x10^14 m^2, show that we could collect enough energy to meet all of humankind's annual energy needs in less than 12 hours.
c) Alternatively, if we wanted to provide all of humankind's energy needs with wind power, how many 100 MW wind farms are needed? (Assume constant average energy use and no efficiency losses.)
What is the correct answer to this and why? Please provide an in depth explanation explaining the various aspects you need to know for this question.
Einstein’s discovery that energy and mass are equivalent had let to technological developments that are both beneficial and dangerous. Discuss three of these developments. Overall, do you think the human race would be better or worse if we had never discovered that mass is a form of energy?
