"Therefore another way to increase lighting efficiency is to buy reflectors for lights so that all of the light produced is reflected downwards. Otherwise 50 percent or more of the light - and energy - escapes into space!

Incidentally the following composite photograph of Earth's cities at night is an excellent example of wasted energy. Imagine how far away this "light pollution" can be seen!"

Well that is a good idea. See:

Imagine how much of the Universe everyone is missing.
