Money and Happiness: China Surveys Suggest a Limited Link

After two decades of extraordinarily rapid economic growth, people in China aren’t much happier than when they started, suggests a new review of happiness and national income in the world’s largest, most economically accelerated country. On the whole, China’s wealthy are slightly happier than before, but little appears to have changed among middle-income earners. Among lower income brackets, life satisfaction seems to have dropped precipitously. These trends are not an argument against capitalism or economic growth — but they do hint at shortcomings in using standard economic metrics as shorthand for well-being. “There is no evidence of an increase in life satisfaction of the magnitude that might have been expected to result from the fourfold improvement in the level of per capita consumption,” write researchers led by economist Richard Easterlin in their May 15 Proceedings of the National Academy of Sciences paper....

German Energy Revolution: Feldheim, German Village, Powered By Renewable Energy

This tiny village of 37 gray homes and farm buildings clustered along the main road in a wind-swept corner of rural eastern Germany seems an unlikely place for a revolution. Yet environmentalists, experts and politicians from El Salvador to Japan to South Africa have flocked here in the past year to learn how Feldheim, a village of just 145 people, is already putting into practice Germany's vision of a future powered entirely by renewable energy. ...

“Power the World” Week – Issue #4: African Huts Far From the Grid Glow With Renewable Power

Thanks to this solar panel, Sara Ruto no longer takes a three-hour taxi ride to a town with electricity to recharge her cellphone.

For Sara Ruto, the desperate yearning for electricity began last year with the purchase of her first cellphone, a lifeline for receiving small money transfers, contacting relatives in the city or checking chicken prices at the nearest market. Charging the phone was no simple matter in this farming village far from Kenya’s electric grid. Every week, Ms. Ruto walked two miles to hire a motorcycle taxi for the three-hour ride to Mogotio, the nearest town with electricity. There, she dropped off her cellphone at a store that recharges phones for 30 cents. Yet the service was in such demand that she had to leave it behind for three full days before returning. That wearying routine ended in February when the family sold some animals to buy a small Chinese-made solar power system for about $80. Now balanced precariously atop their tin roof, a lone solar panel provides enough electricity to charge the phone and run four bright overhead lights with switches. “My main motivation was the phone, but this has changed so many other things,” Ms. Ruto said on a recent evening as she relaxed on a bench in the mud-walled shack she shares with her husband and six children. ...

Join the “Power The World” Twitter Flash Mob!

The United Nations announced this week that they would team up with Linkin Park to provide electricity to the 2.6 billion people that have no or only limited access to electricity. In order to heat their homes, cook for their children etc. many of them have to use dung, kerosene, petroleum and other substances which may present a health risk. One of the aims of the new "Power the World" campaign is to raise awareness. You might have noticed that I've started a series of articles all dealing with this issue during my "Power the World" week. Another way to reach this aim is, of course, to get #PowertheWorld trending on Twitter. As this is most successful if many people tweet this at the same time, I've decided to organize a little flash mob! Date and Time: The flash mob starts tomorrow (Saturday, November 12) at: 11am (CST) USA 12am (EST) USA 5pm (GMT) UK 6pm (CET/MEZ) Central Europe (Germany) 7pm (EET) (Greece) 2am (JST) (Sunday: Japan) 4am (AEDT)(Sunday: Australia) 1. I couldn't include every single country in this list, but I guess the list is an orientation, so that you can calculate the time for yourself 2. I know that the time is quite late/early for Japan and Australia, but firstly, this time includes the most countries, and secondly, we count on you to join us as soon as you've woken up. 3. Please share this information on Twitter, Facebook, Tumblr, LPN, the Linkin Park fansites (LPL, LPT, LPA, MSC, LL, CBN, etc.) What to do: ...

“Power the World”-Week Issue #1: A Light in India

Students in the village of Tahipur in Bihar used kerosene lanterns for studying.

When we hear the word innovation, we often think of new technologies or silver bullet solutions — like hydrogen fuel cells or a cure for cancer. To be sure, breakthroughs are vital: antibiotics and vaccines, for example, transformed global health. But as we’ve argued in Fixes, some of the greatest advances come from taking old ideas or technologies and making them accessible to millions of people who are underserved. One area where this is desperately needed is access to electricity. In the age of the iPad, it’s easy to forget that roughly a quarter of the world’s population — about a billion and a half people (pdf) — still lack electricity. This isn’t just an inconvenience; it takes a severe toll on economic life, education and health. It’s estimated that two million people die prematurely each year as a result of pulmonary diseases caused by the indoor burning of fuels for cooking and light. Close to half are children who die of pneumonia. In vast stretches of the developing world, after the sun sets, everything goes dark. In sub-Saharan Africa, about 70 percent of the population lack electricity. However, no country has more citizens living without power than India, where more than 400 million people, the vast majority of them villagers, have no electricity. The place that remains most in darkness is Bihar, India’s poorest state, which has more than 80 million people, 85 percent of whom live in households with no grid connection. Because Bihar has nowhere near the capacity to meet its current power demands, even those few with connections receive electricity sporadically and often at odd hours, like between 3:00 a.m and 6:00 a.m., when it is of little use. This is why I’m writing today about a small but fast-growing off-grid electricity company based in Bihar called Husk Power Systems. It has created a system to turn rice husks into electricity that is reliable, eco-friendly and affordable for families that can spend only $2 a month for power. The company has 65 power units that serve a total of 30,000 households and is currently installing new systems at the rate of two to three per week. Bringing sustainable light to communities off the grid ...
