Energy Secretary Rick Perry wants to know if wind and solar are compromising the reliability of the grid and hurting coal power. The answer lies in his home state of Texas.
Solar provides tremendous opportunities for emerging entrepreneurs.
Africa's energy potential remains under-exploited, the energy entrepreneur is well-positioned to take advantage of the opportunities presented by the energy sector.
Why were so few complaints about wind farms investigated further? And who made these complaints anyway?
Have the hordes of wind farm complainers all gone shy?
Over a period in which the Australian economy saw around 600,000 additional people get jobs, employment in the renewables sector has been going backwards.

Estimates released by the Australian Bureau of Statistics suggest that the number of direct full-time equivalent jobs in renewable energy activities has continued to fall from its 2011-12 peak.
To manage renewable energy efficiently, all weather variation need to be taken into account.
Relying less on fossil fuels is one of the key challenges of energy transition, and taking weather variations into account can help increase the overall efficiency of a renewable-energy system.
Engineers are hoping to iron out a century-old technology that could reduce shipping emissions.
Peak energy demand sometimes occurs when there’s no wind.
Here are some short- and medium-term strategies for transitioning to renewable, reliable and affordable energy in South Australia.
Even the cleanest coal plants add millions of tonnes of greenhouse gases to the atmosphere each year.

Nobody in business wants to touch new "clean" coal plants, which means taxpayers would be left to foot the billion-dollar bills.
With the right mix, the grid can go fully renewable for the same cost and reliability as fossil fuels.
The Turnbull government is funding energy storage as a crucial missing piece of the electricity grid puzzle. Analysis suggests an affordable, fully renewable grid doesn't require any heroic assumptions.
Watt a good idea.
Many believe we can stabilise the power supply by asking customers to help - but there's a problem.

Skirmishes over funding for renewable energy research are just the latest battle in a saga that stretches back to the early 1980s – years before the public became widely aware of the climate threat.
Companies like Tesla, with batteries and electric cars, are disrupting traditional energy companies in Australia.
Energy companies shouldn't rely on government regulation to protect them from the growing disruption from renewables and increased consumer control.
