Coal stockpile at a Milwaukee, Wisconsin power plant, 2011.
A recent study shows that large piles of coal produce measurable quantities of fine particulate air pollution within a 25-mile radius. Covering coal trains and storage piles could reduce the problem.
Using solar power could give the U.S. military some advantages – and more security.

US military bases usually get their electricity from the civilian grid, which is vulnerable to attack and to disaster. Solar-powered microgrids could protect national security, and would save money.
Lake Liddell with power stations.
We need to remember that baseload coal power stations won't help cope with peak demand – the issue that will determine whether people in elevators are trapped by a sudden blackout, per Barnaby Joyce.
Energy Minister Josh Frydenberg accused AGL of wanting to have its cake and eat it too.
If anyone thinks the government isn’t behaving in a extraordinary manner in its onslaught against AGL over the future of the Liddell power station, just consider what the Coalition would say if a Labor…
There are many viable options for Australia’s energy future.
The energy market operator has warned of possible future electricity shortages – but only if everything stays frozen as it is now.
A man fixes electric wires in the Lagos Island district. Nigeria has serious power challenges made worse by the way the sector is regulated.
The centralised regulation of electric power in Nigeria is stalling progress in the sector. To achieve stable power supply, the country must obey its constitution and decentralise regulation.
Drax and Eggborough power stations in England.
Why go to all that bother when you can just half-fill the kettle?

On Q&A, an audience member said renewable energy is 'now cheaper than coal'. Senator Matt Canavan disagreed, saying renewables are not 'at the moment, cheaper than coal'. Let's look at the numbers.
The first U.S. offshore wind farm, near Block Island, Rhode Island, started delivering commercial electricity in December 2016.

When utilities plan investments, they think decades ahead. A recent study shows why power companies should be spending more on renewables despite the Trump administration's tilt toward fossil fuels.
A single, national market that supplies all of Australia’s electricty is looking dangerously outdated – and politically impossible.
The idea that Australia's national electricity market is either useful or feasible has simply passed.
The controversial Narrabri coal seam gas project. Australia has plenty of gas reserves that are cheaper to develop and a safer bet.

Australia has enough gas reserves to supply the next 25 years' demand. Federal pressure to lift state bans on onshore gas development is pointless, risky – and won't bring prices down.
Australia will need more sources of zero-emissions energy if it is to stay on track for carbon-neutrality by 2050.

A new analysis by ClimateWorks Australia says that the electricity sector needs to do far more to cut its carbon emissions than will be delivered by current policies.

Data suggests a smart-meter plan to shift electricity use to off-peak hours has had almost no impact.
A tanker ship heads into Liverpool harbour as a pilot boats heads out. In the background. In the background, the Burbo Bank wind farm. While new facilities have increased capacity, the UK currently imports 6% of its electricity.
A year after Brexit, experts from the Grenoble École de Management and the Centre for European Economic Research look at what impacts the UK's leaving the EU could have on energy prices and security.
The Finkel Review is scientifically modest but politically deft.
Chief Scientist Alan Finkel has attempted to address the energy 'trilemma': electricity that's cheap, reliable and low-emissions. Has he succeeded? Our expert panel weighs in.
The Finkel review aims to introduce certainty into Australia’s energy market.
The Finkel review is designed to create a coherent and realistic plan for a low-emissions future. Here are the details you need to know.
Australia is awash with options for low-emissions energy.

A new report from CSIRO outlines four pathways for Australia to hit our Paris climate targets, and get cheaper energy at the same time.
The forecast for future blackouts in Australia doesn’t look good if there’s no change in our energy demand and supply.
Better energy management could reduce peak demand by the equivalent of two Hazelwood power stations. It's time to get serious about demand response solutions to our energy crisis.
Current political intervention in the energy market is haphazard and disconnected.
The energy security crisis has politicians leaping to unveil various schemes. But we don't need piecemeal action – the Finkel review, due in June, aims to create a coherent new energy blueprint.
South Africa’s power utility, Eskom, desperately needs a tariff hike.
South Africa's power utility Eskom wants regulatory reporting requirements waived. The country's regulator faces possible court action if it agrees.
