Following the Fukushima Daiichi nuclear disaster, Japan has struggled as many of its nuclear power plants remain off the grid, forcing the country to turn to expensive foreign gas imports. A new report however by Wood Mackenzie highlights the potential wind power has for transforming the Japanese energy mix. Could a great leap see Japan become a wind powerhouse?

Sports stadiums around the world are turning green, adopting solar and wind technology to improve their cities and win over fans

Scientists from Stanford University have developed a microbial battery using 'wired microbes' to create power from sewage and wastewater. The technology, though small in scale, shows early promise as both an electricity source and an exciting new treatment for wastewater.

The majority of power technology innovations and breakthroughs in 2013 occurred in the renewables sector. Power-technology.com lists some of 2013's major innovations and breakthroughs in energy technology. Ultra-efficient photovoltaic designs A four-junction solar cell, developed by Germany's Freiburg-based Fraunhofer Institute for Solar Energy Systems, Soitec and two other research organisations, achieved a record breaking 44.7% efficiency converting sunlight to electricity in September 2013.

The International Ashden Awards champions some of the most interesting and life-changing sustainable energy projects created at a grass-roots level for local communities.

Empowering women through clean power technologies has been put firmly on the agenda thanks to recent events held by the United Nations and Ashden Awards. So how is clean tech changing lives and how can it be scaled up to game-changing levels?

A South Korean university has come one step closer to developing wireless power by improving both efficiency and transmission distance, a breakthorugh which its developers believe could lead to wireless energy becoming as popular as WiFi in the not to distant future.

$1.8bn Agua Caliente Solar farm is a 290MW photovoltaic (PV) power project located in the east Yuma County of Arizona, US. It is owned by NRG Energy and MidAmerican Energy Holdings and is currently the world's biggest photovoltaic solar power plant.

The 115MW El Arrayán wind power plant will be the largest wind energy facility in Chile once complete. Located about 400km north of Santiago in the coastal zone of Ovalle, the project was developed by Parque Eolico El Arrayan, a joint venture between Pattern Energy and Antofagasta Minerals.

Researcher Alexa Spence has spent years looking at the psychological issues around recent advances in energy technology, from uncovering the value of the 'freeloading' flatmate in reducing domestic consumption to studying how businesses can motivate staff to reduce energy usage.

The perennial argument for maintaining significant fossil fuel capacity is this: when the wind doesn't blow, and the sun doesn't shine, and the mercury drops low enough that the whole country simultaneously dials up the thermostat, then renewables on their own are not enough to keep the lights on

The decision by Iraq to invite interest in a number of solar independent power producer (IPP) projects is not the first time that Baghdad has sought to push ahead with competitively tendered IPP schemes.

Britain's ability to generate green electricity is growing, but with utility-scale solar farms typically covering up to 100 acres of land or more - usually in rural areas - is it good news for wildlife?

The European Commission has given the UK Government the go ahead to offer EDF a guaranteed price per unit of electricity generated for a 35-year period for the purpose of incentivising investment. Ever since it was first proposed in October 2013, the proposed deal between the UK government and French nuclear power company EDF for the financing of a new nuclear plant has courted controversy.

There are many job opportunities in the wind energy sector, with more vacancies expected to arise as the industry expands globally. But what skills does it take to cope with often hostile conditions, towering structures and unpredictable wind supply? UK-based offshore wind farm site manager Derek Whyte divulges all.

Tidal Lagoon Power is seeking approval for a £12bn project to develop a series of tidal energy plants in the UK that is claimed to be the world's first tidal lagoon power plant.

20 February 2014 The US Department of Energy (DOE) has announced it will approve approximately $6.5bn in loan guarantees for the construction of two new Westinghouse AP1000 nuclear reactors at the Alvin W. Vogtle electric generating station, also known as Plant Vogtle, in Georgia.

The UK announced a £7bn package in the 2014 budget to reduce energy costs for British manufacturers and households by 2019, and GDF Suez launched the Sohar 2 and Barka 3 gas-fired combined cycle gas turbines (CCGT) plants in Oman.

Jasper solar power project is a 96MW solar photovoltaic (PV) power plant being developed in Northern Cape Province near Kimberly in South Africa. The plant will become one of the biggest solar power plants in Africa, upon completion. The project will be developed and operated by California-based solar developer SolarReserve and its consortium partners Kensani and Intikon Energy.
