selection15: More Profit with Less Carbon.

       Many argues that protecting earth's climate will increase the cost of meeting society's needs for energy. Environmentalists, on the other hand, say the cost would be higher indeed but worth it. In other words, protecting the climate would reduce the costs by using energy more efficiently. Improving the energy efficiency is doing more with less, and it is what many confuse now with privation which is doing less, worse or without. Enhancing efficiency is the most vital step toward creating a climate-safe energy system.

• THE ENERGY REVOLUTION.
  Many energy efficient products, that were once costly are now inexpensive, for instance, compact fluorescent lamps that now cost only 2$. In the 90s Pacific gas and electric undertook an experiment called ACT that demonstrated that large efficiency improvements can be cheaper that small ones, for example building a suburban tract house that could indeed stay cool in the summer without any air conditioning.
• VEHICLES OF OPPORTUNITIES
  in the US only, transportation consumes 70% of its oil and generates a third of the nation's carbon emissions. However, transportation offers enormous efficiency opportunities. In other words, combining lightweight materials with innovations in aerodynamics could cut oil use by vehicles by two thirds without compromising comfort, nor safety and performances.
  However, modern cars lack any astonishing efficiency as only 13 percent of a car's fuel energy reaches the wheels. The solution to achieve the energy efficiency when in comes to cars, is simply by reducing the car's weight
• RENEWABLE ENERGY

alternatives to coal-fired power plans, including renewable sources began to hit their stride. Despite the obstacles that face generators and competition, the collective generating capacity is still growing rapidly. Wind power is the biggest success story, considering its mass production in many countries.
