Will China make the world green?

Joschka Fischer was never one to mince words when he was Germany’s foreign minister in the late ’90s and early noughts. So it is not overly surprising that he has painted a picture in a new post of a world with only two powers — the United States and China — and an ineffective and divided Europe on the sidelines.

More controversial, however, is his view that China will not only grow into the world’s most important market over the coming years, but will determine what the world produces and consumes — and that that will be green.

Fischer, who was leader of  Germany’s Green Party, reckons that due to its sheer size and needed GDP growth, China will have to pursue a green economy. Without that, he writes in his Project Syndicate post, China will quickly reach limits to growth with disastrous ecological and, as a result, political consequences.

This will have serious consequences on the the way the West lives.

Consider the transition from the traditional automobile to electric transport. Despite European illusions to the contrary, this will be decided in China, not in the West. All that will be decided by the West’s globally dominant automobile industry is whether it will adapt and have a chance to survive or go the way of other old Western industries: to the developing world.

This is not the usual view of China. Many greens have long feared the impact of a huge leap in Chinese growth on the global environment — refrigerators in a billion homes, cars in a billion garages etc.

So instead of killing the planet, is China set to save it?

Green energy – Definition and meaning

The simplest green energy definition would be energy produced from energy sources that are environmentally more friendly (or “greener”) compared to fossil fuels (coal, oil, and natural gas). Green energy therefore includes all renewable energy sources (solar, wind, geothermal, biofuels, hydropower), and by definition should also include nuclear energy though there are many environmentalists who oppose the idea of talking about nuclear energy as the green energy because of the nuclear waste issue, and its harmful environmental effects.

Green energy term was coined to separate highly polluting fossil fuels from other less polluting, environmentally friendlier energy options such as renewable energy sources. Climate change has become a global threat, and world needs to find cleaner (less emitting) energy options, and thus the importance of green energy keeps growing.

Green energy is still not powerful enough to compete with fossil fuels. This is mostly because green energy is still significantly more expensive energy option compared to fossil fuels, and thus many countries, especially developing ones, rather stick with cheaper fossil fuels such as coal.

It also has to be said that term green energy doesn’t include only renewable energy sources but can in more broader term also include the conservation of energy (for instance a green energy example is also a building constructed in a way that it keeps itself cool in the daytime and heated in the night through its architectural design instead of relying on air-conditioning or a heating system).

The promotion of green energy does not only include using more renewable energy sources in years to come but also to make currently dominant fossil fuels energy technologies more greener and less polluting (such as clean coal technologies).

Term green energy is sometimes identified with the term sustainable energy but this is not entirely correct because sustainable energy also includes technologies that improve energy efficiency. Green energy doesn’t refer to efficiency of renewable energy sources but is only interested in their positive environmental impact (compared to fossil fuels).

USPS Goes Green

In strict adherence to guidelines released by the Department of Energy, the United States Postal Service gets on a fast track to reach the goal for energy reduction. Green roofs, green buildings and an optimally efficient management system of energy consumption form part of the energy-reduction strategy.

Power Guzzlers:
Use of air conditioning is one of the main reasons for the ever increasing power consumption. The heat-island effect also plays a part. Concentration of black or dark roofs and paved surfaces raise the ambient temperature increasing the demand for air-conditioning. The air quality also is certainly poorer because of the ever increasing carbon emissions.

Going green:
The agency is aggressively marching on to reduce power consumption. The plan is to economize energy consumption by 30% by 2015. It is using various approaches to reach the goal. Already 70% target completed, only about one third of the goal is all left to achieve by the USPS.

Cool roof initiatives:
One of the remarkable initiatives in combating power consumption is the cool green roof initiatives as per Energy Department guidelines. In Manhattan Midtown, the USPS has converted the roof of Morgan Mail Processing Facility to green roof topping. This 2.5-acre wide green roof is the largest green roof topping in New York City.

Advantages of Green roof:
Not merely meeting the early performance estimates, this green roof has actually exceeded all expectations since the time it was constructed. The advantages are:

Cool green roofs reflect sunlight and reduce heat gain.Reduction of polluted storm water run-off-
