>>This is a fair point, I concede that energy use will decrease.<<
While individual use may decrease, global consumption is likely to continue to increase - exactly as it has in every other year. The Population Problem. People really don't realize the magnitude of the problems that this planet is facing. From the post to which I linked:
When you actually think about the effects of the population increase, the realities of the situation start to hit home. The population is growing at a rate of 1.5 million per week. To put that number in perspective, in order to house all those people in a single place you'd need to build a city the size of Phoenix each and every week, or a city the size of New York every 5 weeks. Before the end of next month, the world's population will have increased by more than the current population of Sweden. Before the end of the year, it will have increased by more than the current population of the UK. Before the end of 2013, it will have increased by more than the current population of the US.
To think that we can meet the needs (electricity, transportation, food, clothing, etc.) of all these extra people while decreasing global energy consumption is crazy. It's simply not going to happen. And renewable energy is a recipe for disaster. Also from the post to which I linked:
We are already seeing an extinction crisis (from Wikipedia: The 2008 Red List was released on 6 October, 2008, at the IUCN World Conservation Congress in Barcelona, and "has confirmed an extinction crisis, with almost one in four mammals at risk of disappearing forever." The study shows at least 1,141 of the 5,487 mammals on Earth are known to be threatened with extinction, and 836 are listed as Data Deficient). How much worse will that crisis become as we start erecting more solar panels, more wind turbines and diverting more waterways? And how much worse will it become as our cities and agricultural areas expand by 50% during the course of the next 5 decades? How long can our already depleted oceans supply fish for a population that is increasing by 1.5 million per week?
Sorry, but covering country-sized tracts of delicate ecosystems with solar panels and wind turbines is not an environmentally-responsible course of action!
