Scotland has approved ten marine energy projects that leaders predict could provide electricity for one-third of the nation’s homes by 2020 and make Scotland the world leader in wave energy.

The government awarded leases to companies to construct six wave energy projects and four tidal project off the Scottish coast in what experts say would be the first developments of their kind on a large commercial scale.

Construction would cost £4 billion ($6.1 billion) and require another £1 billion ($1.53 billion) in government funding to upgrade the national electric grid. But First Minister Alex Salmond said tapping into the resources of Pentland Firth, a strait north of Scotland that is known for its strong tides, can make the country the “powerhouse of Europe.” (more…)

California recently approved the decision of a state-wide solar heating program consisting of almost $360 million financial incentives and market development funding by 2018. This initiative will soon be followed by rest of the country that lagged behind the world in installing solar thermal systems.

Global statistics show that the solar thermal industry is taking large steps in fulfilling heating and cooling demand in the world. Most of the countries around the world have adopted incentive programs for both solar water heating and space heating. Whereas in some countries, solar thermal systems have been widely utilized for so many years even without incentives.

The most important decision criteria for a household to install a solar thermal system is basically the payback times of their investment. The main driving factors of the investment payback time are the total cost of the systems and the cost of alternatives heating systems. (more…)

A new 42-floor London skyscraper will be the world’s first building to incorporate wind turbines in the design, an innovation developers say will generate 8 percent of the building’s electricity needs.

The Strata Tower, a 408-unit apartment building scheduled to open in July, will be topped with three 19-kilowatt turbines — each with five 29.5-foot blades designed to suck wind from various angles and accelerate it through tubes, generating as much as 50 megawatt-hours of electricity annually.

It will also generate about £16,000 to £17,000 annually through the nation’s new feed-in tariff, the developers say. (more…)

More than 235 U.S. scientists, including some of the nation’s most prominent climate researchers, are recommending new procedures for the U.N.’s Intergovernmental Panel on Climate Change (IPCC), including acknowledging errors on the organization’s website as soon as they are known.

In an open letter, the scientists, some of whom have contributed to IPCC reports, defend the quality and transparency of the panel’s research. But they suggest the IPCC should become more responsive in acknowledging mistakes and should publish an erratum online that corrects any errors discovered after publication. (more…)

The harnessing of solar energy is expanding on every front as concerns about climate change and energy security escalate, as government incentives for harnessing solar energy expand, and as these costs decline while those of fossil fuels rise. One solar technology that is really beginning to take off is the use of solar thermal collectors to convert sunlight into heat that can be used to warm both water and space.

China, for example, is now home to 27 million rooftop solar water heaters. With nearly 4,000 Chinese companies manufacturing these devices, this relatively simple low-cost technology has leapfrogged into villages that do not yet have electricity. For as little as $200, villagers can have a rooftop solar collector installed and take their first hot shower.

This technology is sweeping China like wildfire, already approaching market saturation in some communities. Beijing plans to boost the current 114 million square meters of rooftop solar collectors for heating water to 300 million by 2020. (more…)

(Reuters) – New forecasts suggest the European Union will exceed its target of getting 20 percent of its energy from renewable sources in 2020, the European Commission said Thursday.

The latest national projections submitted by governments to the E.U. executive suggest the 27-nation bloc could reach an overall renewable share of 20.3 percent by the end of the decade.

“These forecasts show that member states take renewable energy very seriously and are really dedicated to pushing their domestic production,” E.U. Energy Commissioner Guenther Oettinger said.

Spain and Germany forecast the largest surpluses in 2020, predicting they will exceed their national renewable targets by 2.7 and 0.7 percentage points respectively.

This will help to make up for projected shortfalls in several EU countries, including Italy, which expects to miss its 17 percent target by 1 percentage point. (more…)

As surely as last year’s Paris fashions make their way west to New York, U.S. utilities are beginning to embrace European-style programs like feed-in tariffs and green power premiums.

State-level decoupling regulations are easing that transition to some extent. But many utilities are still reluctant to embrace the change fully, especially as prices for conventional energy have come back down and utilities are finding that available capacity in voluntary green power is going unsubscribed.

Utilities do not like the financial uncertainty posed by long-term contracting for renewable power to supply the programs if they are not going to be able to move the power. It inevitably puts the utility’s shareholder obligations at odds with its ratepayer obligations and results in one of two solutions: green premiums go up and make the company look bad on green; or, everyone on the system pays to cover the nut, and no one is happy.

More than one-third of the carbon dioxide emissions associated with consumer goods used in developed nations is actually emitted in other nations where the products are made, according to a new study.

In the United States, about 2.5 tons of carbon produced per person annually — or about 11 percent of U.S. per capita emissions — are emitted elsewhere, researchers at the Carnegie Institution for Science say.

In Europe, it’s about four tons of carbon per person. In fact, in smaller European nations like Switzerland, the emissions associated with products manufactured outside the borders exceed the actual emissions produced at home. (more…)

The British government will introduce legislation that would tie new, subsidized loans for energy efficiency to a house, rather than a current owner, a move that could make energy retrofits far more affordable for most homeowners.

Energy and Climate Secretary Ed Miliband said the new legislation would enable homeowners to take out long-term loans at lower interest rates and thus encourage homeowners to make energy-efficiency improvements that they might otherwise not have made had they planned to sell their houses in a few years.

Biofuels in Europe are struggling to meet the most basic thresholds for sustainability, according to the Times of London, which claims to have seen a government study that shows fossil fuels are better for the environment than “green fuels” made from crops.

The findings show that the United Kingdom’s biofuels mandate would result in millions of acres of forest being logged or burnt down and converted to plantations.

The study finds that some of the most basic crops used to make biofuels fail to meet the minimum sustainability standard set by the European Commission. (more…)
