Hydrofracking impacts water quantity, too

Hydrofracking impacts water quantity, too

Posted Mon, 16 May 2011 22:59:00 GMT by Michael Clark

Much of the debate swirling around hydrofracking centers on water quality impacts, obscuring its potential impacts on water quantity. What is undeniable is that the practice called high volume hydraulic fracturing requires large volumes of water, potentially impacting local water supplies and aquatic habitat.

Boost biofuels by tackling 'glitches' in photosynthesis

Boost biofuels by tackling 'glitches' in photosynthesis

A paper published in Science tomorrow outlines how the less-than-perfect natural process of photosynthesis could be boosted, by tackling areas of known deficiency. That could give plants being used for biofuels a leap forward - putting sustainable plant-based energy into the realms of reality.

Why fickle wind power wins out over nuclear

Why fickle wind power wins out over nuclear

Whilst yesterday's Renewable Energy Review pushed the UK's nuclear button firmly - as a solution to reducing greenhouse gas emissions - it's in fact a time to hit the pause button. Nuclear power will be a costly dangerous diversion from the real solution - making truly renewable energy sources into a reliable foundation for our future energy needs.

The UK's Climate Change Committee threw its weight behind a greater role for nuclear power, in order to achieve renewables targets of 15% by 2020, and 30% by 2030. As part of a broad review of the renewables sector, asked for by the governing Coalition, the road-map set out sees a mix of 'low-carbon' energy sources - but a slow-down in the push for offshore wind farms.

Scheme to help developing countries reduce emissions reaches important milestone. The UN's Clean Development Mechanism (CDM) which is designed to help reduce greenhouse gases from developing countries has reached 3000 projects: a wind farm in Inner Mongolia, which is a province of China.

Dr Frank Neumann of the School of Computer Science at the University of Adelaide is using this approach to determine the best placement of turbines on a wind farm to enhance their productivity. The project involves collaboration with researchers at the Massachusetts Institute of Technology.

Are 'brownfield' sites the renewable power generators of tomorrow? Landfill, disused mines, redundant industrial sites and even rooftops are all starting to look like attractive locations for renewable energies generators such as solar power, wind turbines and even biomass production. All we need is the commitment from business and government to put them to good use.

US wind power strategy won't be stymied by warming climate

US wind power strategy won't be stymied by warming climate

Global warming is unlikely to suck the power out of a US wind farm energy solution. That's the good news to come from a paper in this weeks Proceedings of the National Academy of Sciences, which projects strengthening winds in many areas slated for wind farms. The paper helps to fill in a worrying blank on the possible knock-ons to renewables due to climate change.

Google's drive to make renewable energy cheaper than coal power energy is a long term mission. Since launching the initiative, Google has cut investment in renewable energy technology companies while increasing investment in renewable power generation schemes, most notably with a recent $100 million investment in the world's largest wind farm in Oregon, US.

The authors of a new report from Berkeley Lab may paint a rosy picture of China's future emissions, seeing them as peaking much earlier than other analysts - but sadly it may still be too little, too late, unless we all take our foot off of the global gas pedal.

Biofuels are predicted to be supplying over a quarter of the world's transport fuel market by the year 2050. As the world struggles with rising petrol and diesel costs, biofuels are increasingly being seen as the most viable alternative source. However, this will come at a cost.

25 years on, the world remembers history's worst nuclear disaster. Just after midnight on 26 April 1986, the Chernobyl nuclear power plant, just 60 miles north of the Ukrainian capital Kiev, exploded. Over 350,000 people were evacuated. It was, and remains, the world's worst nuclear disaster.

Green Energy From Estuaries

An estuary is defined as being the mixing zone where fresh river water meets the salt water of the ocean. The penetration of salt water into the fresh river water can extend backwards from the coast for some distance. Researchers at Stanford University recently published details of a battery which uses changes in salinity to produce electricity (see Nano Lett., 2011, 11 (4), pp 1810-1813).

Fukushima: A Rush to Nuclear Energy Judgment?

At the start of this piece, let me nail my colours to the mast: I am a proponent of nuclear energy and I have worked on the periphery of the nuclear industry. What has slowly emerged since a devastating 9.0 magnitude earthquake and ensuing tsunami hit north east Japan on the 11th of March has served to show how ignorant the world is about radioactivity and risk.

Hydrogen-powered cars, laptops and mobiles could be a step closer, thanks to the discovery of a practical - and cheap - alternative to sky-high priced platinum. Platinum is currently the best catalyst for hydrogen fuel-cells. But the new carbon-iron-cobalt catalyst, described in today's Science, works as well as platinum, and its low cost could pull hydrogen power out of the shadows into a brighter renewable future.

Tepco puts a roadmap in place to end the crisis at the Fukushima nuclear plant by the end of the year.The operators of Japan's stricken Fukushima nuclear plant are implementing a nine month roadmap, ensuring the crisis will be resolved by the end of 2011. Fresh concerns were raised last week when, on Friday, levels of radiation in the sea near reactor 2 were measured to be 6,500 times the legal limit.
