Humanity’s fight against climate change is failing. One technology can change that.

By Akshat Rathi – The optimism surrounding renewable energy masks some harsh realities. Despite decades of progress, about 80% of the world’s energy still comes from fossil fuels—the same as in the 1970s. Since then, we’ve kept adding renewable capacity, but it hasn’t outpaced the growth of the world’s population and its demand for energy.

Today, about 30% of total world energy (and 40% of the world’s electricity) is supplied by coal, which emits more carbon dioxide per unit of energy produced than nearly any other fuel source.

The hugely valuable oil and gas industries, accounting for 33% and 24% of total world energy use, respectively, are also entrenched. “Based on what we know now, we would need major technological breakthroughs or weak world growth, including for large emerging and developing economies, for oil demand to peak in the next 20 years,” says Gian Maria Milesi-Ferretti of the International Monetary Fund. Despite the growth in electric vehicles, most oil companies agree that peak oil is “not in sight.”

If you’re still not convinced, consider this: there are a handful of industries essential to the modern way of life that generate large amounts of carbon dioxide as a side product of the chemistry of their manufacturing process. These carbon-intensive industries—including cement, steel, and ethanol—produce about 20% of all global emissions.

If we want to keep using these products and reach zero emissions, the only option is to have these industries deploy carbon capture. more>

Carbon Capture and Green Technology

By S. Julio Friedmann – The world is emitting more carbon dioxide than even the worst-case IPCC models allow. In 2010, roughly 35 billion tons of man-made CO2 entered the atmosphere — about 70 times the weight of all human beings on earth. That annual volume is about seven billion tons more than it was in 2004, largely because of rapid economic growth in developing countries.

Unfortunately, energy technology, on the whole, has not evolved fast enough to cope with the CO2 problem. Novel nuclear reactor research continues, including new fuel cycles (like thorium), proliferation-resistant designs, new “inherently safe” designs, and lower-cost approaches. However, the tragedy of the tsunami-induced reactor failures in Japan has delayed the deployment of new nuclear technologies. more> http://twurl.nl/posymb
