What a gas: one of Moreland’s new hydrogen-powered garbage trucks.
A local council goes for hydrogen. A state government goes for lithium and mirrors. They are taking punts on technology. What are the risks?
The BedZED eco-housing development in the UK challenged planning regulations.
Traditional urban planning is being stretched by the pace at which renewable energy systems are being installed. New codes and guidelines are needed to manage emerging conflicts over land use.

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.
Solar PV outstripped coal as the leading source of new electricity generation worldwide last year.

Solar PV and wind energy have overtaken coal as the leading sources of new electricity generation worldwide, with falling prices and new storage technologies making clean energy ever more attainable.
Eco-houses at Scotland’s Housing Expo, Inverness. What is it like to live in a house like this?
There's an international push towards low-emissions housing. New research investigates what it's like to actually live in low-energy houses.
A single, national market that supplies all of Australia’s electricty is looking dangerously outdated – and politically impossible.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.
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.
Malcolm Turnbull is firm in his belief that his party is one of harmony and robust discussion. But Tony Abbott seems to have other ideas.
Tony Abbott's second major public intervention this week prompted a radio interviewer to ask Malcolm Turnbull whether his leadership was under threat.
Josh Frydenberg’s task of garnering broad support for the Finkel scheme is proving to be more difficult than expected.
The degree of pushback against a clean energy target was stronger than had been anticipated, given the intense lobbying of the backbench Josh Frydenberg had done ahead of the meeting.
The government faces a hard internal sell on the Finkel plan, not least to Tony Abbott.
Bedding down an energy security policy based broadly on the Finkel model is now crucial for Malcolm Turnbull. But the issue will also test Tony Abbott’s judgement and influence, in what has long been a…
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.
It's just not in their business interests to ignore climate change.
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.

Earlier this year Australia's energy market operator warned of a gas shortage, sparking fears of an energy crisis. But new research shows the projected shortfall is so small, it may already be closed.
Hydro electricity will be part of Australia’s energy future.

Energy security requires both short and long planning. Recent gas and hydro announcements are a promising start towards some proper joined-up thinking.
A boy silhouetted against smog while playing cricket in Karachi, Pakistan, in 2011.
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.
