An ongoing discussion: how to measure life satisfaction, success, well-being? Recently, the new edition of the Happy Planet Index (HPI) endeavours to contribute a measure for the success of states to provide or allow a happy life to their current and future citizens. Including average life expectancy aims at a most obvious element of life satisfaction; being alive is quiet fundamental for being happy after all. The quality of life on the other side is highly subjective. While material wealth is clearly not enough, a certain affluence or at least security undoubtedly adds to general life satisfaction. In any ... [more]

The world is embracing change and planning for the future technology and lifestyles. Just how will for example cities of the future look like? In Tianjin, China builds its vision of such a city and somehow misses the point. While numerous communities are making successful efforts to move from a car friendly to a human friendly, walkable and cyclable city design, China’s planers seem to pursue an hopelessly outdated US model from the 70s with huge car thoroughfares, parking lots everywhere and basically no way to move around without cars. Granted, the roads are supposed to be occupied by electric ... [more]

Natural gas production and consumption is linked to Methane leaks that almost outdo the lower greenhouse gas emission of natural gas compared to alternative fossil fuels. In order for natural gas to have a positive effect on climate change, methane leakages needs to be cut by 2/3 a very ambitious target that is not likely to be reached anytime soon. Now that’s really interesting and basically outdoing any greenhouse gas benefits of natural gas. Conclusion, let’s move on to comprehensive life cycle analysis for assessing the most suitable energy sources. Conclusion two, while natural gas is more CO2-efficient it still ... [more]

By producing 22 gigawatts of solar power per hour, German rooftops supplied 50% of the country’s electricity needs on a sunny Saturday in Mai. ON-green-policy! Just for the record, Germany is no developing nation with a majority of the population off the grid, but one of the most developed country with a very energy intensive economy and living style. And, I might add that conditions for solar panels – even on a sunny day – are nowhere as favourable as in large parts of the US. Granted, the demand is lower on a Saturday but even on a working day, ... [more]

Investments in green energy overtook investment in fossil energy in 2010. The US took in $48 billion in public and private financing, making it the gobal leader of renewable energy development. So far, good news for the USA. On the downside, much of this investment was triggered by expiring federal tax incentives and will not happen again next year. Also, China is now adding much more green jobs because it not only develops green technology but it is also actually building green energy facilities. By 2020, 150 million more Chinese homes will be powered by renewables! ON-green-energy! If the already ... [more]

US President Obama does not allow uranium mining in the Gran Canyon. Withstanding pressure from the industry and Republicans, he protected 1m square acres in the natural treasure from mining operations. On-green-policy. It sounds like a no-brainer. The Grand Canyon is one of the beautiful sites in the United States and still will be in thousands of years. The uranium that could be mined there could only fuel the US nuclear power plants for a short period of time and its operation and its waste would seriously pollutes the environment over a very long period of time. I argue that ... [more]
