Technology was purely responsible for some of the inventions that made life easier. This same cause also made us to consume much energy so the world, through various agency or groups, made some measures to address this issue. One thing is the solar energy panels, which is quite expensive. Inexpensive means include the use of fluorescent lights in place of incandescent and the use of natural gasses instead of fossil gas sources. The continuous innovation brought by technology will gradually fix the problem it has also created, so in full time, balance would be restored.
