Western Australia wave energy project on the brink of commercialisation

Western Australia wave energy project on the brink of commercialisation
Australia could be set for a breakthrough in energy derived from waves, following the launch a major new project in Western Australia. Carnegie Wave Energy unveiled three large buoys in Perth on Wednesday as part of a new $70 million technology which will feed energy into the Australian grid later this year. The enormous buoys, called buoyant actuators, will be towed out into the ocean near Garden Island, off the coast of Perth. The buoys will then be submerged and attached to underwater pumps. The movement of the ocean’s waves will cause the buoys to shoot high-pressure water through pipes which, in turn, will drive turbines and generators onshore, creating electricity. The high-pressure water will also be fed into an onshore desalination plant, creating fresh water without the need for pumps. Electricity and water provided by the project will be used by the department of defence for HMAS Stirling, Australia’s largest naval base, which is on Garden Island.

UK guarantees £2bn nuclear plant deal as China investment announced Image copyright EDF Energy Chancellor George Osborne has announced that the UK will guarantee a £2bn deal under which China will invest in the Hinkley Point nuclear power station. Mr Osborne, who is in China, said the deal would pave the way for a final investment decision on the delayed project by French energy company EDF.

GE Makes Energy Efficiency 'Current' It seems as though an “All-of-the-Above” energy strategy is no longer simply for policymakers. General Electric on Wednesday announced a new business, called Current, which will strive to improve energy efficiency for companies around the globe. Connecting GE’s LED, Solar, Energy Storage, and Electric Vehicle businesses with its powerful Predix platform, which identifies and delivers cost effective and efficient energy solutions, the new company seeks to revolutionize energy efficiency for businesses.

The world's first solar-powered bike path is generating more energy than expected It’s been one year since an innovative solar-paneled bike path was laid in Krommenie, Netherlands, and the results have even surprised the designers. Over the past year the path has generated 70 kilowatt-hours per square meter - enough to power about three houses. The people behind SolaRoad are hopeful the path’s success will spur more cities to adopt the idea and use existing roadways to gather cheap and sustainable energy. Over 9800 kWh of energy was generated from trails of space that, until now, had been collecting no energy at all.

One million households ditch the Big Six energy suppliers However, the vast majority of UK households are still languishing on the expensive standard tariffs of one of the Big Six suppliers - British Gas, SSE, EDF Energy, E.On, ScottishPower and npower. Ministers and regulators are still grappling with how to encourage more households to shop around, with millions of families failing to do so despite average savings of hundreds of pounds on offer. The Competition and Markets Authority announced this week it was extending its ongoing inquiry into the sector as it tries to come up with suitable remedies to address the lack of consumer engagement. Ed Kamm, chief customer officer at First Utility said: "The dramatic growth of independent suppliers is testament to consumers wanting something different – lower energy prices and better value from their provider.

This could be the biggest sign yet that the battery revolution is here The California Inland Empire Utility Agency’s solar panels, located at three of the Agency’s recycled water facilities and IERCF, generate 3.5 MW of clean solar power and will reduce electrical costs at its facilities — the single largest component of IEUA’s operating budget. The solar project is funded in part under the State’s Innovative California Solar Initiative. (Inland Empire Utilities Agency/John Mellin) We may be getting a real time glimpse of a world that energy visionaries have long awaited — one featuring a large scale merger between clean energy technologies, like wind and solar, and large batteries that can store power from these sources and make it available at will. Meet Advanced Microgrid Solutions, based in San Francisco and headed by former Arnold Schwarzenegger chief of staff and California Public Utilities commissioner Susan Kennedy.

Renewable Energy Gains Greater Opportunity in US Clean Power Plan - Renewable Energy World After a year of being pummeled by opponents, Obama’s final carbon reduction plan emerged this week with an even stronger push for renewable energy. Wind and solar energy are centerpieces of the Clean Power Plan, the United States’ first ever rule to reduce carbon dioxide from power plants. The rule not only makes renewables one of the plan’s three central building blocks, but also creates special incentives to spur communities to build renewables more quickly than required. The revised version of the rule comes after a year of review, hundreds of meetings and 4.3 million public comments delivered to EPA. It requires that states come up with plans to cut carbon pollution from power plants by 870 million tons, or 32 percent below 2005 levels, in 2030.

Storing solar, wind, and water energy underground could replace burning fuel Using wind, water, and solar electricity for everything, instead of burning fuel, with resulting improved energy efficiency, means you need much less energy (credit: The Solutions Project/data: Stanford University) Stanford and UC Berkeley researchers have a solution to the problem of storing energy from wind, water and solar power overnight (or in inclement weather): store it underground. The system could result in a reliable, affordable national grid, replacing fossil fuel, they believe. How it would work The Future of Renewable Power in Mexico - Renewable Energy World The abundance of diverse renewable energy resources, growing demand for power, macroeconomic stability, and historically high electricity prices continue to position Mexico as one of the most attractive destinations for investments in renewable power generation. Despite enjoying some of the highest wind and insolation levels in the world, Mexico has yet to develop most of the potential of its renewable energy sources. As of 2013, thermal sources represented 75 percent of Mexico’s installed capacity, followed by hydropower generation, which accounted for 19 percent of total capacity, while other renewable sources, such as wind, solar and geothermal energy represented less than 6 percent of electricity generation in Mexico.
