Electricity pylons from Cape Town’s Koeberg nuclear power plant. State-owned companies help to provide infrastructure for economic development.
State-owned companies are not generally needed to provide goods. Rather, they are needed to provide the foundation for a well-functioning economy and a healthy, well-informed populace.
‘Not a goosebump between us.’
While the Paris climate talks focus on technical fixes, no one talks about how we're much more afraid of roughing it than ever before.

By 2030 renewable energy sources such as solar and wind will cost a similar amount to fossils fuels such as coal and gas, thanks to falling technology costs
A large solar thermal plant in Morocco will provide energy for 1m people – here's how it will work.
Gas is the solution to some but not all our problems.
UK's decision to close coal power plants is really a statement of the obvious, and does nothing to answer the problem of what to do afterwards.
When it comes to gas vs renwables, it seems the balance isn’t right.
Who'd want to take part in the UK energy economy when the government keeps changing the rules?

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.
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.
Nanotechnology that can detect illnesses will become available next year.
A novel approach to detect bacterial infections in 10-15 minutes is expected to become commercially available next year.
The Supreme Court will decide a case that will have a big effect on distributed energy technology, including batteries.

Solar hot water is an excellent way to heat up without adding to your electricity bill. Unfortunately, it seems Australians are not getting the most from their solar hot water systems.
Gas bill got you feeling grey? A reverse cycle air conditioner could save you money.
Heating your home using electricity is not just cheaper, it's more efficient and can be considered renewable.
Businesses that emit large amounts of greenhouse gases will have their emissions capped.
Australia's new cap on emissions includes aspects of a "baseline and credit" emissions trading scheme. That's cheaper for businesses, but means more regulation.
Now regulated for carbon emissions.
How the US ended up regulating carbon emissions using the 1970 Clean Air Act rather than a national cap-and-trade emissions trading system.
Gas may no longer be the most economic way to heat your home.
Eastern Australia's gas market is rapidly changing, driven by the first exports of liquefied natural gas (LNG) from Queensland. And this is affecting the whole supply chain, from gas producers, to the way we use gas in our homes.
Current + lack of current = a headache for phycists.
We may have to rewrite physics textbooks after a material that can act both like a conductor and an insulator simultaneously has been discovered.
Energy efficiency has driven the recent fall in electricity demand.
In June this year, forecasts revealed residential and business demand has risen for the first time in five years. The trend could be here to stay, according to a report released today from the Australia Institute.
