Read about how the scientists attributed as having agreed upon the existence of global warming were named without their consent, nor had they voiced any such affirmation on the matter.
Global warming is a fallacy; a red herring being used to line pockets and consolidate power in global policy bodies like the UN. If you have actually bothered to step outside recently or looked at temperature trends for the past several years, you'd notice we are amidst a global cooling trend. This has nothing to do with greenhouse gases. It is due to lower levels of solar output, particularly in relation to sunspot activity.
Oh, and by the way, the new scare term is "global climate change".
Carbon footprint is the son of the-artist-formerly-known-as-global-warming and inheritor to the throne of red herrings. Carbon dioxide, which is purported to be at the center of the crisis, is a life gas. Many people might argue that having stuff around that promotes life is a good thing. More carbon dioxide contributes to greater plant growth and oxygen production, which helps us be more active and think more clearly. Carbon dioxide is at the lowest levels it has been in recorded history. It is hardly a problem. If anything, we need more carbon dioxide, and less scare-mongering pseudo-science... and maybe a refresher in seventh grade earth sciences.
That said, we have a planet awash with hydrocarbons, wind, solar radiation, and water. All of these are energy sources we can harness today and simply don't, or constrain our production of raw material or energy derived from those sources.
Look, we are on a planet which has teamed with life for millions of years. Given that oil derives from living matter, it is inconceivable that we have managed to locate or use anywhere near all of it in the last century. Even if this were not the case, we have a plethora of known oil reserves we've yet to tap which have been put off limits to drilling for little or no reason, other than the duplicity of politicians and oil companies. Have a look at the U.S. National Geological Survey maps.
Water is a hydrogen fuel storage source with its own combustive catalyst, oxygen, built right in. I mean, we drink what could potentially be our most inexhaustible terrestrial fuel source. The planet is more than two-thirds covered with ocean, and we have even more locked up in tundra ice, freshwater, and cloud systems. It's as insane we don't make use of it as it is that we don't use more steam-powered engines capable of more work for less energy.
Supplemented with wind turbines and solar converters, we'd be so completely independent of energy concerns that we wouldn't even be having this discussion on power savings.
You want to save some energy, get a hybrid conversion kit for you vehicle that lets it use water as a supplemental fuel source. Get a small wind turbine or solar panels and pull your deficit off the grid during your peak usages and sell power to the electric company by pushing your excess out to the grid during low usage. Insulate, insulate, insulate.
Oh, and anyone who doesn't like me exhaling because it raises my carbon footprint and contributes to global warming... well, they can just hold it in until they are blue in the face.
