Five Surprising Facts About Energy Poverty
Business as usual “will not remotely suffice” to meet goals of clean and universal energy, says a World Bank-led report.
Solar powered plane lands in NYC after Historic Flight Across the US
Its like the Wright brothers all over again but this time with zero-carbon emissions! Love this story.
From the Guardian: “A plane entirely powered by the sun touches down in New York late on Saturday in the final leg of a journey across the US. The Solar Impulse began its trip over two months ago. The experimental aircraft has four propellers driven by energy collected from 12,000 solar cells in its wings which charge its batteries for night use”

Meet Eesha Kare, who invented a device that charges cell phone battery in under 30 seconds
Eesha Khare, 18, of Saratoga, Calif. received the Intel Foundation Young Scientist Award of $50,000. With the rapid adoption of portable electronics, Eesha recognized the crucial need for energy-efficient storage devices. She developed a tiny device that fits inside cell phone batteries, allowing them to fully charge within 20-30 seconds. Eesha’s invention also has potential applications for car batteries.

Energy harvesting pavement powers its own streetlights.
London-based startup Pavegen has developed tiling that can harvest kinetic energy from people’s footsteps, turning it into up to 8 watts of electricity per footstep.
The tiles are made of 95 percent recycled tyres, and use a proprietary wireless communications technology to transmit data about the number of footfalls and the energy generated via the Internet. A wireless network of the tiles could provide valuable information to city planners and nearby business owners about the number of pedestrians in the area at different times of the day.
At the last Summer Olympics in London, the tiles were installed outside a tube station where they generated enough energy to power lights in the area for five hours a night.
As the trend toward wireless-enabled personal devices grows worldwide, the biggest energy drain in the wireless cloud will clearly come from mobile 4G LTE and wireless networks in general which are expected to account for 90 percent of energy use by 2015 compared to 9 percent by data centers. All together, the amount of energy used by the wireless cloud could increase by as much as 460 percent between 2012 and 2015. According to the report, that’s the equivalent of putting 4.9 million cars on the road. “Finding solutions to the ‘dirty cloud’ at the very least requires a broader acknowledgment of the cloud computing ecosystem and each components’ energy requirements,” the report says. “There needs to be a focus on making access technologies more efﬁcient and potentially a reworking of how the industry manages data and designs the entire global network.”
