Solar panels in Alexandra, Johannesburg.
The value of green technologies and systems is that they are largely decentralised or semi-decentralised.
Used once and done.
Research is yielding strategies for making plastics greener and more sustainable. But without support as they scale up, new versions will struggle to compete with well-established synthetic plastics.
Looking through semitransparent cells – one day these could be big enough to make windows.
Solar windows would need to trap enough light to generate power, while letting through enough to keep buildings light. Thankfully, newly developed semitransparent cells offer to do just that.
With some tweaks to the recipe, cement and concrete can be made kinder to the planet.
Cement has a huge greenhouse footprint, largely because the chemical process by which it is made releases carbon dioxide. But there are several different ways for cement to green up its act.
When manufacturers are chasing sales and more and more customers are plugging in, is the writing on the wall for F1?
Seabubbles and docking concept.
French company Seabubbles provides new transport concept which aims to see the people of Paris using water instead of roads.
Uncertainty around government policy affects how businesses operate and whether they’ll invest in R&D.
Economists have shown, using both theory and data, that uncertainty about U.S. environmental policies makes clean tech innovation less likely.
Lee: 'Business will be far from usual in a world of four, five or six degrees of warming.'
Might the sun set on this technology before it’s even taken off?
Solar panels and roads — combining them just makes sense to help meet our clean energy needs, right? Maybe not quite.

Imagine a wind turbine, but underwater, not fixed to the seabed, and able to work 24/7.
The Kariba dam on the Zambezi River produces most of the electricity used in Zimbabwe and Zambia, supports extensive fishing and tourism industries and protects hundreds of thousands of people from floods.
Green infrastructure may not be the best thing for Africa despite being environmentally friendly.
A green trade deal would encourage the development of renewable energy in big carbon emitters such as China.
Ten years on from the Australia-US Free Trade Agreement, Australia is entering another round of negotiations towards the new and controversial Trans-Pacific Partnership. In this Free Trade Scorecard series…
Battery costs can make up a quarter of the cost of an electric car such as this Tesla Model S.
At the heart of the current debate around energy is the question of storage. In cars, how to build batteries that run for hundreds of kilometres; in electricity, storing energy from solar panels for when…
Small, but not for long.

There is increasing talk of electrification of the UK’s railway network. But electrification is an expensive business, requiring much new hardware including masts, wiring, substations and so on. Such an…
