What do I (we) do about my (our) carbon footprint?

A very frequent question asked by students after learning about climate change is “But what can I (we) do about it?”. Here are some ideas, all of which have benefits in addition to reducing greenhouse gases, and so are worth considering even if you reject the idea of anthropogenic global warming completely.

OLD Wind Turbines

The total energy available in wind and the power that can feasibly be extracted from it will be determined using the fundamentals of kinematics. The limitations of location and machinery of wind turbines that restrict the amount of power that can be harnessed will also be examined, before comparing the impact of wind energy with various other common sources of energy.
