I am, as a consumer, confused. Every time I think I know something (based on some study) it appers that there comes out another study that is giving the opposite results. For example, I thought that diesel cars are more environmental friendly than cars that use gasoline. I think that I read that from some paper. Sometimes later it appeared that that diesel cars have problem with emission of particles,which makes them not so environmentally friendly at all. And then the hybrid cars. I thought that they are the environmentally friendly cars (if they can be such a thing), being advertised with that theme, but then I read some study from a paper that actually the manufacturing of the cars takes so much energy and materials that they are worse than off-road vehicles (read about that here). And are biofuels really the solution to the problems with petroleum. Some instances claim that biofuels are the biggest reason for global trend of incresing costs of food.
And now it appeared that using computers actually cause environmental problems, because of taking so much energy. One search by Google uses as much energy as use of energy saving light bulb for one hour. Here is some news how Google tries to save energy.
As a conclusion: life appears to be full of surprises and various truths. It is difficult for consumers to pick up the right truth.
