Before jumping into the home battery market, make sure you do your research.
The 'early adopters' of home battery storage will pay significantly more than those who come later, but it won't be long until prices drop enough for many more to get on board.
The U.S. could dramatically increase solar and wind power without expensive energy storage. The key is to overlay high-voltage direct current power lines on our system of regional grids.
A solar array goes up in New York. Is this the best place to locate solar, given the relatively clean New York state grid?
The wind and solar industries scored a huge win by getting extended tax credits, but research shows this isn't the best policy for lowering emissions through renewable energy.

Strength in numbers matters in the world of solar energy.
South Africa has installed solar water heaters in low cost housing areas. It should be installing solar PV for energy.
South Africa has been slow to adopt renewable energy sources. One option, which has proved successful elsewhere, would be to install solar photovoltaic panels on rooftops in low-income areas.
Small solar panel installations can provide electricity and jobs, while not adding to emissions.

Much of India's huge population is still without electricity, perhaps making climate action a tough sell. But India's vision for green development chimes well with the world's climate agenda.
It's not easy powering a network of billions of sensors. But this could be a solution.
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.
Rooftop solar panels: will they kill power companies or can they help them?
Many utilities see rooftop solar as a threat, but solar power can actually lower the cost of power they – and their consumers – need to pay during hours of high demand.
Renewable energy developers choose sunny locations, which can be near protected lands.
Study shows that many of the utility-scale solar power plants in California have been placed near protected and environmentally sensitive lands.
Solar energy is key to development in African countires.
Integrated research is key to sustainable development, which helps Africa resolve its energy woes.
Australia has 1.4 million solar rooftops. But it is with the addition of battery storage that energy grids will really be revolutionised.

New prime minister Malcolm Turnbull has stressed the importance of embracing 'disruptive' technologies that shake up existing business models. Solar power and battery storage is one of the most enticing options.
Australia has some catching up to do to match the rest of the world on large-scale solar.

New funding for large-scale solar could be backing a winner, but only with the right leadership.
To no one’s surprise, a US study found that solar panel cells produce infrasound and low frequency noise which is way below audibility.
Internoise is the world’s premier research conference for acousticians. The 2015 meeting is being held right now in San Francisco. Buried among the hundreds of papers is one that you could easily take…
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?
Townsville’s roads (pictured) may have their busy periods but is it the best place to start a solar charged ‘electric super highway’?
If you want to kick-start the "electric superhighway" in Queensland then it makes sense to start in a populated area with the busiest traffic.
Is the price right for installing solar panels?
Victoria's solar will soon get a mere 5 cents for power they send to the grid. But is that a fair price?
California has realised that investing in renewables is smart economic policy.

Ramping up investment in renewable energy would put Australia on a footing with competitors such as China, Germany and California, which are set to reap the economic benefits of this emerging sector.
Is the sun setting on Britain’s energy ambitions?
In the long run a shift from renewables to fossil fuels will make it harder to reach emissions targets and will harm the UK's international standing.
