Green Options

With billions in stimulus dollars heading toward improving the electricity grid and building sustainable energy infrastructure, emission-free power may be coming to your neighborhood sooner than you think. Here are five of the biggest, most ambitious projects that are in the pipeline, both in the US and elsewhere.

Russian Prime Minister Vladimir Putin has approved a government order to increase renewable energy in Russia from less than 1% to 4.5% of the nation’s total energy by 2020.

The Kremlin’s order to ramp up renewable energy has set targets of 2.5% by 2015 and 4.5% by 2020. That translates into 45.2 billion kiloWatt hours of renewable energy production by 2020, based on the country’s current electricity production.

To reach these goals, the government will fund small hydro, tidal, geothermal, wind, solar and biomass energy facilities. Wind energy, for instance, is slated to expand from 12 MW (2005) to some 7000 MW by 2020.

Developing Russia’s economically recoverable renewable energy could cut some 990 million tons of CO2 emissions a year, according to the Organization for Economic Cooperation and Development (OECD). (PDF) To put that number in perspective, it would be the equivalent of preventing two-thirds of the CO2 emissions of the United States from entering the atmosphere. This estimate, as well as Russia’s renewable energy statistics, doesn’t take into account large hydroelectric projects, which already account for 21% of Russia’s total energy.

Renewable energy is starting off right in the new year with the “Electric Power Annual 2007″ report from the US Energy Information Administration. According to the newly released report, non-hydroelectric renewable energy is now the leading source of new electric generating capacity in the US.

A UK engineer has invented a device that harnesses wave power to pump sea water uphill, from where it can flow downhill to create hydroelectricity, raising hopes of a cheap, abundant source of renewable energy.

In trials, the device, called the Searaser, has pumped water more than 160ft above sea level, using little more than the natural motion of the waves. There are now plans for a much larger version, capable of pumping to a height of more than 650ft.

Inventor Alvin Smith reckons that each full-size device would be able to pump enough water to supply electricity to 470 homes. He also calculates that a fleet of 43,000 could generate enough power for a staggering 20 million households.

In our search for new clean technology, it’s important to pay attention to inventions of the past. A tiny hydroelectric plant in the Yorkshire Dales area of England is coming out of a 60 year retirement next summer to create renewable energy.

Despite their tumultuous economy, Iceland is vying for one of the non-permanent United Nations Security Council seats going up for a vote tomorrow.

Iceland, which generates nearly all of its power from geothermal and hydroelectric sources, has emphasized their valuable experience in the fight against climate change and said they would represent the goals of all small countries with their position on the council.

Not every country has Iceland’s volcanoes, geysers, and hot springs to tap for electricity, but President Olafur Ragnar Grimsson is convinced that all nations possess the natural resources to cut their fossil fuel use and that doing so is vital for global security.

SmartPlanet report that British Waterways is turning UK canals into alternative energy power stations. The company’s proposal calls for 50 wind turbines and assorted small-scale hydro-power schemes to be installed in canals and locations. In addition to generating enough energy to power 45,000 homes (100 MW of capacity), the proposal will save over 100,000 tons of CO2 each year.

Many dams in Southwest China sustained significant damage after the recent massive earthquake.

The Min River and its tributaries have 30 dams upstream from Dujiangyan and 16 incurred significant damage from the recent earthquake. The Zipingpu dam is an example where a dam failure could have disastrous consequences.

Zipingpu dam threatens millions

The Zipingpu reservoir can hold a staggering 1.1 billion cubic meters of water, but the dam wall was cracked after the earthquake. Dujiangyan, with a population of 600,000 would be devastated by a dam failure first. Within a couple hours, water would then hit the provincial capital, Chengdu.

In case you missed them the first time around, here are the top 10 international environmental headlines that made news in the blogosphere for the week of March 31 - April 6.

1. Asia — United Nations Climate Change Talks: “Kyoto II” climate talks open in Bangkok

“The first formal talks in the long process of drawing up a replacement for the Kyoto climate change pact opened in Thailand on Monday with appeals to a common human purpose to defeat global warming.

‘The world is waiting for a solution that is long-term and economically viable,’ U.N. Secretary-General Ban Ki Moon said in a video address to the 1,000 delegates from 190 nations gathered in Bangkok.
