Most countries dependent on foreign sources for renewable technology materials

Source: Renewable Energy Focus

The Geological Society of America has warned that most countries are highly dependent on foreign sources for the rare metals used in photovoltaics, wind generators, fuel cells and high capacity batteries. Solar PV for instance often requires gallium, indium, selenium, tellurium and high quality silicon, whereas batteries need zinc, vanadium, lithium and fuel cells need metals in the platinum group.
China is one of the biggest providers of these metals but it seems that increasingly they are being withheld for Chinese domestic use. According to a new report from the Worldwatch Institue it also appears that China is starting to become dominant in the renewable energy sector and has ambitions to be a global leader in renewables.
  • In 2009, China overtook the US as the world's largest market for windpower
  • Chinese windpower capacity has doubled every year for the past four years
  • In 2009 China's PV companies held 40% of the global market, with most production exported to Europe. More than 20 Chinese companies have successfully engaged in initial public offerings (IPO's) and five of these are among the world's top ten in solar PV production.
  • China's solar water heating capacity accounts for 80% of global installations.
  • China is the world's largest manufacturer of solar water heaters. Chinese manufacturers now hold 90% of the market for these products.
  • China reduced its energy intensity (energy use per unit of GDP) by 15.6% between 2005 and 2009 and is on target for 20% by 2010.
  • China's energy consumption doubled since 2000 although per capita energy use remains well below the world average.
  • Consumption of coal in China has doubled over the past nine years and consumption of oil tripled.
  • China wants to reduce its carbon emissions per unit of economic output by 40-45% by 2020. It projects renewables as representing 16-20% of total energy consumption by 2020 and 40-45% by 2050.

The Battle of the Blogs? Whitlock goes to War...

Good day folks, you're all in for a bit of a treat as it happens, so I hope you're sitting comfortably. Before I go any further, I should issue a 'long read' warning. This blog piece is going to be fairly long, quite involved in its detail, but hopefully very enjoyable if you despise and detest climate change denial, as I do. But first, an explanation of the circumstances.

The other day, on Twitter, I indulged in a bit of regular fun-poking at James Delingpole, as I often do because, quite simply, the man just invites it. For those not in the know, Delingpole is a pretty nasty character really. He writes regular blog pieces and op-eds for Breitbart and The Spectator, usually on climate change, but also on other subjects as well. He is usually, and seemingly, unashamedly vicious, as will become apparent in my coverage of him and his behaviour in this piece. Given his behaviour, I am not afraid, occasionally to indulge in a bit of 'ad-hominem' warfare myself, ind…

5 Companies and Their Efforts to Reduce the Environmental Impact of Manufacturing

By Rana Tarakji
The Industrial Revolution has undoubtedly affected the environment. From pollution to global warming, the environment has taken on a lot of the burden for many of the advancements that humans have enjoyed.
Unfortunately, the manufacturing industry is one of the biggest contributors to the significant damages and hazards on the environment. Manufacturing companies are among the biggest producers of solid, liquid, and gaseous wastes that lead to huge levels of pollution.
Although many manufacturing companies still do not have policies and practices in place to reduce their negative impact on the environment, there are many who are taking the lead to a more sustainable and environment-friendly approach.
Coca Cola When it comes to beverage manufacturers, Coca Cola is among the biggest around the world. They have started taking on a more responsible environmental commitment by making water preservation, sustainable packaging, and energy and climate protection among their goals.…
