Government commitment to support investment in low-carbon technologies would secure significant savings for UK consumers

Government commitment to support investment in low-carbon technologies would secure significant savings for UK consumers | Développement durable et efficacité énergétique | Scoop.it

"In a report on the Electricity Market Reform published today, the Committee on Climate Change presents new analysis showing that there are significant economic benefits from investing in a portfolio of low-carbon technologies through the 2020s rather than investing in gas-fired generation."

Stephane Bilodeau's insight:

"A failure to commit to this would be to bet on a low gas price world, which could lock out the much higher benefits from portfolio investment in low-carbon technologies in more likely scenarios. It would be a wager on an outcome that is the opposite of most expectations. Even if the proposition were true, and a low gas price world were to ensue, cost savings due to investment in gas-fired generation through the 2020s would be very limited."

Lord Deben, Chairman of the CCC said:“This Report shows that there are significant benefits and very limited risks from investing in low-carbon technologies. It factors in the potential benefits of shale gas, which could play a useful role in meeting heat demand. It shows that the cost-effective route to the 2050 target involves investment in a portfolio of low-carbon technologies in the 2020s. However, in order to secure maximum economic benefit for the UK, it is crucial that the Government gives certainty to investors by legislating to chart a clear course well beyond 2020. Only then will we be able to insure against the risk of much higher future energy prices; enhance Britain’s energy sovereignty; and protect ourselves against dangerous climate change.”

Applaud Efforts To Turn Britain's Isle Of Wight Into A Self-Sufficient Island of Renewable Energy | Développement durable et efficacité énergétique | Scoop.it
Over the past decade, efforts in environmental stewardship have increased exponentially. Now being green, clean, and using renewable and sustainable energy sources are ways of life. More and more organizations are bending to the demands for efficient and unpolluted products, leading to a surge in green technologies and sustainable farming techniques. Such awareness and effort is truly commendable and has sparked impressive energy projects all over the world: one of the most recent being David Green’s Ecoisland project on Britain’s Isle of Wight. Within the past year, the Ecoisland project has become world-renowned due to its goal to make the small island a self-sufficient haven of renewable energy by 2020. Such prowess and devotion to environmental health is truly a praiseworthy cause that deserves applause and recognition.

U.S. Energy Efficient Hydropower Upgrades Get More Power from Dams

U.S. Energy Efficient Hydropower Upgrades Get More Power from Dams | Développement durable et efficacité énergétique | Scoop.it

The U.S. has 2,400 hydropower dams, many of which sport out-of-date generating equipment that is, well, generations old. That’s the bad news. The good news is, it all adds up to the potential for a massive energy efficiency upgrade program that could significantly boost U.S. hydropower generation without the monumental expense and environmental disruption involved in new dam construction. In fact, the first round of hydropower upgrades is already underway at an average cost of less than 4 cents per kilowatt-hour.

A successful story of solar stimulus

A successful story of solar stimulus | Développement durable et efficacité énergétique | Scoop.it

A recent front-page story in the Cape Cod Times uncovered a situation where the American recovery and Reinvestment Act (the ARRA – remember that?) has been successful.  And since it involves sustainability and since the words “project manager” and “jobs” were featured heavily throughout the story, we thought we’d share much of it with you here.

Third-Party Financing For Renewable Energy

The third-party financing method is used to make the most out of a diverse resource mix. One participant may have real estate ideal for a renewable energy project; the other may have capital and/or expertise to facilitate the investment purchase. There are many types of third-party financing within all the renewable technologies. The benefits to both the host and the investor vary.

KfW to lend Germany €100bn for renewables deployment

KfW to lend Germany €100bn for renewables deployment | Développement durable et efficacité énergétique | Scoop.it
German development bank KfW will provide the country with €100bn as it shifts to a renewable energy-focused economy.

The country made the bold move to carry out a shutdown of its nuclear plants after the Fukushima disaster in March 2011 but after reducing subsidies its homegrown solar and other renewable energy companies are suffering.

According to a report in Reuters, KfW will make available loans of more than €100bn for both renewable energy and energy efficiency.

Four Must-See Charts Show Why Renewable Energy Is Disruptive – In A Good Way

A common refrain, from skeptics to allies alike, is that renewable energy is a great idea, but not feasible because oil, gas, and coal will always be cheaper.

Willy De Backer's curator insight, May 12, 2013 6:37 AM

The price of renewable energy has always been the false debate. If political and economic elites would have understood the real challenge of finite energy, the price tag would be the least of their worries. The REAL problem with renewables is the non-renewable scarce resources you need to produce, manufacture and deploy them.

New study: There is enough wind potential on Earth's surface to power human civilization 100 times over

New study: There is enough wind potential on Earth's surface to power human civilization 100 times over | Développement durable et efficacité énergétique | Scoop.it

At the moment, wind power supplies about 4.1 percent of electric power in the United States. Still a bit player. Yet there’s a whole lot of untapped wind left in the world. Wind whipping through the Great Plains. Wind gusting off the shores. Wind circulating high up in the sky. So what would happen if we tried to harvest all of that wind?

 

We’d have enough energy to power the world. At least in theory. A new study published this week in Nature Climate Change finds that there’s enough wind potential both on the Earth’s surface and up in the atmosphere to power human civilization 100 times over. Right now, humans use about 18 terawatts of power worldwide. And, technically, the study found, we could extract about 400 terawatts of wind power from the Earth’s surface and 1,800 terawatts of power from the upper atmosphere.

 

Even the most optimistic near-term projections for wind power, however, tend to be more restrained. In 2008, the U.S. Department of Energy released a comprehensive report estimating that wind power could provide, at most, 20 percent of U.S. electricity by 2030. And for that to happen, the cost of wind power would have to keep plunging, the number of turbines built would have to steadily increase by about 14 percent each year, and utilities would have to build new transmission lines to accommodate the extra energy.

King Natural Gas

King Natural Gas | Développement durable et efficacité énergétique | Scoop.it
Will cheap natural gas give us an opportunity to reduce ­emissions while inventing new technologies? Or will we simply become addicted to another fossil fuel?

 

This MIT Technology Review article on the American natural gas revolution might be a bit too optimistic about the future of gas and a bit too negative on the future of renewables, but it has some very valid arguments.
