People in Pitt Meadows and Maple Ridge failed to turn their lights out Saturday during the annual Earth Hour challenge to reduce electricity consumption.

Peabody Energy Corp., one of the world’s largest coal miners, said the industry will continue to rely on China and other developing nations as the U.S. uses less.

Here’s what the St. Louis company expects for the coal market in 2012:

Spain saw wind power become its main source of electricity generation last month, underscoring the country's progress in becoming one of Europe's greenest nations.

The Japanese nuclear disaster has focused attention on global energy resources and nuclear power's role as a source of electricity.

Now is an opportune moment for Japan and the United States, in particular, to undertake a thorough re-examination of their current energy environments and to develop robust new energy policies to address both domestic and international energy use.

Nikola Tesla once dreamed of being able to harness electricity from the air. Now, research being conducted at Brazil’s University of Campinas (UC) is indicating that such a scenario may indeed become a reality. Professor Fernando Galembeck, a UC chemist, is leading the study into the ways in which electricity builds up and spreads in the atmosphere, and how it could be collected. “Our research could pave the way for turning electricity from the atmosphere into an alternative energy source for the future," he stated. "Just as solar energy could free some households from paying electric bills, this promising new energy source could have a similar effect."

Scientists once believed that water droplets in the atmosphere were electrically neutral, even after having come into contact with charged dust particles. Galembeck and his UC team, however, have shown that this isn’t the case. In a lab experiment, they noted that tiny particles of silica and aluminum phosphate became negatively and positively charged (respectively) when circulated in highly-humid air. “This was clear evidence that water in the atmosphere can accumulate electrical charges and transfer them to other materials it comes into contact with,” Galembeck explained. “We are calling this 'hygroelectricity,' meaning 'humidity electricity'.”

He now pictures collectors, not unlike solar cells, that could someday collect and distribute hygroelectricity from the air. Just as solar cells work best in sunny places, his collectors would do best in humid parts of the world. He even believes it’s possible that by diminishing the electrical charge in the air, his collectors could prevent lightning, especially if mounted on top of tall buildings. His team is currently experimenting with different metals, to find out which would work best for capturing atmospheric electricity and preventing lightning strikes.

"These are fascinating ideas that new studies by ourselves and by other scientific teams suggest are now possible," he said. "We certainly have a long way to go. But the benefits in the long range of harnessing hygroelectricity could be substantial."
