Energy security requires both short and long planning. Recent gas and hydro announcements are a promising start towards some proper joined-up thinking.

Massive new coal plants planned for Pakistan will further harm the environment in a country already suffering the effects of climate change. Solar energy is a clear alternative.
Alamosa Photovoltaic Plan, south-central Colorado.
Former Colorado Gov. Bill Ritter, now leading a clean energy research center at Colorado State University, explains why clean energy will keep growing despite President Trump's focus on fossil fuel.
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.
Wind turbines require massive structures that are polluting to produce and can harm ecosystems, but these impacts compare favorably with those of fossil alternatives.
No energy source is perfect, but solar and wind have a much lower health and environmental footprint than fossil fuels, a study finds. Biopower, though, is a mixed bag.
High gas prices have left Adelaide’s Pelican Point power station running at less than half its capacity.
South Australia's government was angry about the blackouts enforced by electricity regulators. But with much of the state's gas power offline, the regulators had little choice.
Solar panels can be both a headache and an opportunity for network companies.

Managing voltage on the electricity network has always been an issue. But solar panels have the potential to make the situation better, not worse as some have feared.
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.
The Inga dams in the DRC generate about 1000 MW of electricity for the country.
Small-scale renewable energy projects have tremendous potential to power rural areas in the DRC. Rural areas in the country have very little access to electricity.
South Africa’s new energy plan shows a greater reliance on gas, solar and especially wind power.
South Africa has a new energy plan. Renewable energy in the form of wind, gas and solar feature high on its agenda.

America's coal heartland is delighted with Donald Trump's election win. But like King Canute, he can't turn back the tide of the global market push away from coal and towards renewables.
The recently updated Integrated Resource Plan calls for significant investment in South Africa's power supply. But can the country afford it?
South African consumers are paying far too much for petrochemicals products.
Raging debates about the state of South Africa's energy industry have missed one critical area, the role of transport fuels and base chemicals.

Wind and solar farms are great. But we need to reduce energy demand and start taking carbon out of the atmosphere.
Koeberg power station, in Cape Town, is the only nuclear power station on the African continent. South Africa is considering a proposal to build more such power stations.
The argument put forward by Eskom that it can handle South Africa's controversial nuclear build programme is fundamentally flawed.
Whitelee wind farm near Glasgow.
Just when you thought wind farms were bad for house prices everywhere, a new piece of research from Scotland suggests otherwise.
Wind and solar power can be intermittent. Should our usage be too?
Christopher Pyne, Malcolm Turnbull and Steven Marshall have all spoken out on renewables in South Australia.
Storage is the issue politicians must deal with if we are to transition away from coal and gas based power generation.
Australia has been a world leader in solar panel development.

An open letter from 190 solar energy researchers in defence of the Australian Renewable Energy Agency, which has funded world-leading research.
Africa has the best solar resource in the world.
Despite having some of the best solar radiation levels in the world, the diffusion of solar energy systems in Africa has been very low
