With the federal cuts to the renewable energy target, the states are stepping up to fill the gap.
Hong Kong: a showcase for Asian urban development.
Nobel Laureates met recently in Hong Kong to sign a memorandum calling for cities to help guard against climate change. As the most creative places on the planet, big cities are the perfect place to meet this challenge.
Still chugging: the operation of existing nuclear plants in the US is being extended far beyond their expected life.

We cannot eliminate the inherent risks of nuclear power but it is rigorously monitored and has a proven performance of delivering zero-carbon electricity.
The drop in oil has not sparked the nadir of green energy.
Contrary to economic theory, data shows that the latest drop in energy prices does not undermine investment in renewable energy.
The cost of low emissions technology is falling faster than modelling five years ago expected, lowering the cost of reducing carbon emissions.
Despite solid results from the first emissions reduction fund auction, Australia hasn't yet got a climate policy to last.
Batteries to store excess solar power will be a game-changer. But energy-efficient appliances will mean you can use a smaller battery.

The unveiling of Tesla's Powerwall home battery has been hailed as a huge moment in renewable energy. But don't forget the other innovations that can help you use that stored power more efficiently.
Amid the fanfare over the launch of the Powerwall, has Tesla’s Elon Musk struck a decisive blow for renewable energy?
Tesla's new home battery could help halve the costs of electricity for typical American households - all using existing technology. The fossil fuel industry is right to be worried.
The SNP wants Westminster to learn from them.
The SNP wants the UK to match Scotland's commitments to carbon reduction.

Consumers of wind power pay twice: first via their monthly electricity bill and a second time as taxpayers to finance billions of dollars in subsidies.
BP’s energy outlook would make it difficult to keep warming below 2C.
BP's Energy Outlook report forecast an increase in fossil fuel use by a third. That would make it difficult to keep warming below 2C.

A new report shows Australia can and should double its energy productivity, increasing economic productivity while reducing greenhouse gas emissions.
Fossil fuels can only go so far towards meeting our burgeoning energy demands.
A non-metal alternative to platinum electrodes in fuel cells could make them an affordable solution for energy security.
The planned wind farm will be four times larger than the current champ - London Array.

Dogger Bank, a popular fishing spot in the North Sea, could soon host up to 400 wind turbines.
Swansea Bay: tidal powerhouse?
A tidal lagoon for Swansea could harness the power of the seas.
Australia likely has several decades of coal left in it yet.
Australia likely has decades of fossil fuels left to extract, export and burn. That could prove to be a problem if the world comes to an agreement on climate change. Here's four ways to help the economy, and the climate.
Wind energy will be an important part of the world’s energy future - but it won’t be enough to feed growing demand.
Peak fossil fuel and action on climate change will mean we have less energy available to power the future.
