there are lots of clever people in the world. many of them make a difference for the better. some even have positions to influence governments. and some make policies for governments. however, it would seem that most decisions are based purely on politics, rather than what is correct, and sometimes their decisions lead to the exact opposite of what they're supposed to be doing, yet everyone seems happy.
LED lighting. the new energy efficient lighting that will save the world from carbon emissions caused from wasteful tungsten filament bulbs! or are they?
well, they do run on a tiny amount of the power of bulbs. and they are much more efficient with much less heat wastage. and they last longer! but how are they made? well, they are made at around 100 times the cost of bulbs. that is real $ cost. which comes from the energy cost. which means over the course of the lifetime, from creation of product to when it is no longer working, they generate more carbon emissions globally. but because they are made outside of europe, european governments are generating less carbon emissions. for themselves. which is all they really want to do.
this is not a unique situation. if you know anyone who has a prius, don't tell them to find out what's in the battery of their car. so many rare earth elements, the mining cost of which no doubt exceeds the carbon emissions saved by using the battery.
answer: real clean fuels (and other energy sources) need to be researched. but whilst government policy only cares about their own country emissions, and researches need government funding, nothing will change.
politics. to paraphrase groucho marx, anyone who wants to be a politician should not be allowed to be a politician.
