Where are we now?

We humans live in a planet called earth. It is a place we inherited from our ancestors. In the past 100 years, technology has developed at a staggering rate. In the 1960's, Bond movies showcased spy gadgets like videophones, small handheld phone gadgets. Now, we have 3G-technology that enable us to do videoconferencing, cellphones that are "do-all" gadgets, and a host of other technologis that we take for granted. But all of these technologies depend on electricity. From the early experimenters like Ben Franklin, Alessandro Volta, Michael Faraday, George Ohm, among others, to the present purveyors of electric power, electricity has spread its influence for hundreds of years.
It is one of the widely used form of energy in the world. In the Philippines, we produced 53.67 billion kWh (2005 data). The sources of electricity are fossil fuel: 55.6%, hydro: 17.5%, nuclear: 0%, other: 26.9% (2001) . Data shows that we burn fossil fuels for electricity more than other sources combined. What happens when fossil fuels are depleted? Naturally, electricity costs will shoot up. Must we wait for this to happen?
