ENERGY
* Access to electricity will reach 83% of the world by 2030. Electrification has expanded around the world, from 40% connected in 1970 to 73% in 2000, and may reach 83% of the world's people by 2030. Electricity is fundamental to raising living standards and access to the world's products and services. Impoverished areas such as sub-Saharan Africa still have low rates of electrification; Uganda is just 3.7% electrified. -Andy Hines, \\"Global Trends in Culture, Infrastructure, and Values,\\" Sep- Oct 2008, p. 20
* Architects will harness energy from the movement of crowds. MIT researchers have created a system of floor blocks that generate power when the blocks rub against one another as people walk over them. A crowd of 30,000 moving to and fro could create enough power to run a small electrical system or perhaps bring a subway train safely to a platform in the event of a blackout. -World Trends & Forecasts, Nov-Dec 2007, p. 6
* Future cars may not fly in the air, but they might run on it. Compressed-air engines are being tested to replace gas-powered engines, achieving speeds of 200 mph. So far, though, they run out of air quickly and still require power to compress the air, so we may not be riding on air anytime soon. -Tomorrow in Brief, Sep-Oct 2008, p. 2
* Capturing carbon will make coal burning cleaner. Carbon Capture and Storage (CCS) could reduce the carbon emitted from coal-fired power plants by as much as 90%. But questions remain as to who should shoulder the costs of implementing the technology (running CCS plants is anywhere from 10% to 40% more expensive than running a traditional coal power plant) and what to do with the sequestered carbon. -World Trends & Forecasts, Nov-Dec 2007, p. 8
* Pursuit of alternatives to oil could help stabilize gas prices. Increased oil production and competition from alternative energy could curtail rising oil prices. New refineries are scheduled to go online in several oil-producing countries by 2010. Meanwhile, the world will have 1,000 nuclear plants operating by 2025. Use of natural gas, wind power, and solar energy will also increase, though to a much lesser degree. -Marvin J. Cetron and Owen Davies, \\"Trends Shaping Tomorrow's World, Part One,\\" Mar-Apr 2008, p. 48
