Scotland: 100% renewable by 2020

Posted Sun, 22 May 2011 14:54:00 GMT by Gracie Valena

Scotland announced on May 20, 2011, that it is targeting to use only renewable energy by 2020, increasing its former target of 80 percent by that year. Scotland First Minister Alex Salmond wants Scotland to become the green energy powerhouse of Europe.

By helping the developing world embrace off-grid renewable energy schemes, the Western world can fulfil the Millennium Development Goals without putting climate change targets in jeopardy.

IEA report says efficient electric-motors could slash emissions

Posted Fri, 20 May 2011 13:41:00 GMT by Martin Leggett

The IEA has produced a report on the future use of electric-motors, showing how a focus on efficiency could help slash electricity demand by 10%. Electric motors use nearly half of all electricity produced in the globe, powering a myriad of industrial, farm and home-based systems. Failure to act could, on the other hand, see emissions rising dramatically by 2030.

The energy-water nexus: EPA proposes water intake regulations

Posted Thu, 19 May 2011 17:53:00 GMT by Michael Clark

The EPA has issued what would be the first national policy on cooling water intake structures. The purpose of the proposed regulations is to reduce aquatic organism deaths associated with impingement on water intake structures. The proposal could have significant impact on water and energy resources.

Greenpeace slams TEPCO's 'utter failure' over Fukushima full meltdown

Posted Wed, 18 May 2011 13:55:00 GMT by Martin Leggett

Greenpeace says that the admission by TEPCO - the Japanese firm in charge of Fukushima - that a full nuclear meltdown was happening, within hours of the earthquake striking, raises many questions. About how the accident's aftermath was handled; about the cover-up culture at the firm, and in the nuclear industry at large; and about whether those in charge of nuclear power can be trusted, now that their perpetual 'safe and clean' claims are blown apart.

$Hydrofracking impacts water quantity, too$

Hydrofracking impacts water quantity, too

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

Posted Thu, 12 May 2011 18:00:00 GMT by Martin Leggett

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

Posted Tue, 10 May 2011 14:22:00 GMT by Martin Leggett

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.

Nuclear crutch needed says UK's Renewable Energy Review

Posted Mon, 09 May 2011 14:26:00 GMT by Martin Leggett

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.

UN Clean Development Mechanism Hits 3,000 Projects

Posted Sun, 08 May 2011 13:15:00 GMT by Julian Jackson

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.

Evolving more efficient wind farms

Posted Thu, 05 May 2011 19:04:00 GMT by Mike Campbell

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.

New York Looks to Landfill for Renewable Energy

Posted Tue, 03 May 2011 21:54:00 GMT by Kieran Ball

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

Posted Tue, 03 May 2011 16:21:00 GMT by Martin Leggett

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 says cheap renewable energy will take longer than expected

Posted Sat, 30 Apr 2011 14:27:00 GMT by Kieran Ball

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.

Rose-tinted report on China's emissions can't dodge bullet

Posted Fri, 29 Apr 2011 16:26:00 GMT by Martin Leggett

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 tipped to fuel transportation sector by 2050

Posted Thu, 28 Apr 2011 10:59:00 GMT by Lucy Brake

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.
