Week 9 (Session 8)

Energy and World Change

Key drivers of the Global Energy Change are the rising energy consumption and the need for economic development, the need to sustainability, and new technology and approaches.

Looking at Energy and World Change, it is essential to look at the 2 different 'parts' of the world. The developed, and the under developed. For the developed countries, unless we are willing to change our habits, we are not able to save the place which we are living in. As for the under developed, how can they make use of Energy in the most efficient way?

E=MC2
The equation of energy where it is equals to the mass of an object, multiply by the square of the speed of light (3 x 108)

That is actually a very large amount. Since energy cannot be created or destroyed, it can only be converted, and almost everything on Earth as a mass so does this mean that every object can create energy for itself? Not quite.

Looking at the slides, it was said that "The Sun provides more every to the Earth than to humankind currently uses in an entire year This shows that here IS enough energy. But how are we going to use the energy from the Sun, or anywhere else for that matter of fact to our advantage?
