Mozambique is seeking to use renewable energy to extend electricity access to rural institutions.
Mozambique has long standing energy challenges and widespread energy poverty. To change this, particularly for people living in rural areas, it needs to democratise the way it supplies energy.
Disase carrying insects are attracted to light bulbs – a constraint of domestic solar energy.
Solar is a vital piece of the energy puzzle for Africa, but there is an insect problem that comes with the light from solar.
A solar water heating unit on the roof of a home in Kuyasa outside Cape Town. South Africa has a long way to go to get people off the grid and onto solar heating.
Africa is blessed with an abundance of sunshine.Given the heavy demand for energy, alternatives, such as solar, could provide solutions and help stimulate economic growth.
Real hot: the Ivanpah solar power plant and others like it use mirrors to produce heat to make steam and drive an electricity turbine.
The massive Ivanpah solar power plant uses natural gas – even more than it expected last year. It's not ideal, but solar power and natural gas are a powerful, and relatively 'green,' combination.
Solar energy is key to development in African countires.
Integrated research is key to sustainable development, which helps Africa resolve its energy woes.
Low carbon choices such as solar power are essential for the African continent, if it intends to stop the harmful global warming effects.
For the sake of mitigating climate change, the African continent needs to make low carbon energy choices.
Access to the grid has crowded out solar in some places in India.

Given existing technologies, expanding access to electricity almost always increases CO2 emissions. There are real trade-offs between addressing poverty and climate change.
Will alternate solar technologies get a boost if solar overall grows?
Hillary Clinton's renewable energy plan is ambitious but, on a technical level, doable. Would it foster more solar technology innovation?
Employers have a duty to keep their employees safe from the sun.
A real-time hand-held device can help employers measure the impact of the sun on workers.
Lots of wind blowing – often at night when there’s little demand for power.
Smoothing out variable wind and solar is a growing problem. Instead of storing energy with batteries, utilities can adjust the power of millions of devices in buildings and homes.
The future of space travel?
A prototype solar sailing satellite has just successfully been deployed in orbit, pointing the way to the future of space travel.
The Tesla Model S - mean, and green?
The Tesla Model S is only as green as its electricity source - which is not very in brown-coal powered Victoria.
A tandem solar cell made from silicon and metal-halide perovskite.
A hybrid approach to solar – using reliable silicon and new inexpensive material perovskite – shows promise for low-cost, efficient solar cells.
Roof-top solar panels are just one part of the micropower revolution.
There is no shortage of shouting and dire warnings about the state of the climate and our need to phase out fossil fuels. But there is a more silent revolution happening too — in micropower. Small-scale…
Battery costs can make up a quarter of the cost of an electric car such as this Tesla Model S.
At the heart of the current debate around energy is the question of storage. In cars, how to build batteries that run for hundreds of kilometres; in electricity, storing energy from solar panels for when…
Wind farms: great, unless it’s not windy.
Australia has some fairly ambitious goals for green energy: a renewable energy target (currently under review) of 20% of electricity from renewables by 2020, and a forecast to get 51% of electricity from…
New, inexpensive materials have been successfully used to create solar-powered fuel. The sun’s rays can drive reactions to…
Researchers from Swinburne University of Technology have developed the world’s most efficient thin film solar cells. The…
Photosynthesis converts low-energy photons into usable energy; it may teach us how to do the same.
As the great spectre of climate change continues to loom large over the future, the search for viable, renewable energy sources is becoming ever more important. Solar power has long been seen as a vital…
Solar is now a viable industry that should be taken seriously.
