Renewable Energy Big Pic: Part 2 Including 19 Charts & Graphs — Reblogged from Cleantechnica

Renewable Energy Big Pic: Part 2 (Including 19 Charts & Graphs) (via Clean Technica)

Continuing on from yesterday’s “Renewable Energy Big Pic” post, here’s Renewable Energy Big Pic: Part 2. As noted yesterday, this two-post series is basically a presentation I gave to a class of renewable energy graduate students this week…

    that there was a significant risk’ that the peak of catnevnionol oil production would happen before 2020, and that means we will soon be staring down the barrel of the ultimate oil crisis.Some governments and corporations are waking up to this and beginning to develop alternatives to keep the worlds transport systems moving when cheap oil runs out, such as more energy efficient or electric cars, bio fuels (which put the world’s food supply under pressure,) and hydrogen (which is too dangerous for public use at present,) but none of these is likely to make up the shortfall in time.Many point to the tar sands and oil shales and the trillions of barrels of oil that are locked up in them, but even if investment in them poured in and everything went well: oil sands might produce 6 million barrels of oil per day in 20 years’ time, but by then we’ll need to add at least 10 times that much capacity without allowing for any growth in demand. It’s very hard to see non-conventional (oil sources) riding to the rescue.’ (Steven Sorrel, lead author of the UKERC report.)There is also the problem that extracting non catnevnionol oil supplies is very environmentally destructive, and if they were fully exploited, would hugely increase CO2 emissions, before they were even burned as fuel.We must also remember that many of the rare earth metals that are needed to develop fuel efficient technologies are only found in China, and they have decided to limit or even ban the export of these metals, leaving all the other countries that wish to expand their use of such technologies at a disadvantage.So the only businesses that can secure energy supplies are those that invest in renewable energies now, before the oil price rises, (due to demand outstripping supply,) and before the costs of making such renewables rises too as a result of resource depletion and the constrained supply of raw materials.
