2010 review of green technologies

In September, the UK opened the world's biggest offshore windfarm at Thanet, off the coast of Kent. The eight lines of turbines, running north-west to south-east, cover a total area of 35sq km off Foreness Point near Margate. With 100 turbines, each 115 metres high with 44-metre blades, it can generate 300 megawatts (MW) of power – enough for 200,000 homes Photograph: Frank Baron/Guardian

In 2010, feed-in tariffs started to generate cash. Householders with small-scale green energy systems such as solar panels and micro-wind turbines receive up to £1,000 a year for the electricity they generate under a new government scheme Photograph: Graham Turner/Guardian

Europe unites to build renewable energy 'supergrid'. It would connect turbines off the wind-lashed north coast of Scotland with Germany's vast arrays of solar panels, and join the power of waves crashing on to the Belgian and Danish coasts with the hydro-electric dams nestled in Norway's fjords: Europe's first electricity grid dedicated to renewable power became a political reality in January, as nine countries formally drew up plans to link their clean energy projects around the North Sea Photograph: Johannes Eisele/AFP

Launch of the Bloom box fuel cell generates a slice of Apple hype. Not every company can boast Arnold Schwarzenegger, Colin Powell and the heads of Google and Walmart at its launch. Even more unlikely, the firm in question makes what some may regard as a less than sexy clean energy device. But such was the razzmatazz that accompanied the unveiling of Bloom ­Energy's eagerly awaited 'energy server' in February Photograph: Justin Sullivan/Getty Images North America

In August, the world's largest tidal turbine was unveiled at a facility in Invergordon, Scotland. The AK1000 was developed by Atlantis Resources Corporation, is capable of generating enough electricity for more than 1,000 homes and is designed for harsh weather and rough, open ocean environments such as the Scottish coast Photograph: Mike Brookes Roper/PA
