COP29 shows how the climate fight depends on an interconnected ecosystem of governments and corporations.
Your electric water heater uses a lot of electricity overnight. Shifting it to soak up solar could be a win-win.
An agreement between an indigenous community and an energy company secured the development of a power plant in exchange for community benefits. But the deal does not meet energy justice principles.
Sub-Saharan Africa is lagging behind in the transition to electric cars and motorbikes. Investment in local manufacturing, renewable energy and storage systems to supply charging stations is needed.
While governments at COP16 make glacial progress on protecting nature, what billions of people choose to do individually can add up to make a big difference.
Pumped hydro and batteries can easily provide all the storage needed for 100% renewable electricity generation, eliminating the need for polluting gas power plants.
Both solar and battery systems costs have just dropped to the point that grid defection will save the average family money, but this could increase emissions in some cases.
By reducing Russia’s revenues from the sale of fossil fuels, could the implementation of the EU’s Green Deal promoted contribute to the stabilisation of Europe? Game theory provides insight.
Integrating biogas, heat and floating solar panels on wastewater ponds could generate enough electricity to supply about 27% of households with renewable energy.
Vice President Kamala Harris has strongly supported clean energy investments, while Donald Trump has railed against them. But transformative shifts in the energy landscape already are well underway.
China has spent ten times more on clean energy than either the US or Europe over the past five years.
The rapid shift in our electricity system calls for a huge increase in the workforce needed to construct, operate and maintain it. Urgent action on building up this workforce is needed.
Solar is becoming a major player in electricity generation and scientists are trying to boost its efficiency still further.
It seems increasingly clear the Coalition’s nuclear policy would prolong Australia’s reliance on fossil fuels, at a time when the world is rapidly moving to far cleaner sources of power.
With more than 200 wastewater ponds, New Zealand has an untapped opportunity to install floating solar panels to increase renewable generation and to reduce algal growth in the ponds at the same time.
Just 14 of Auckland’s largest building rooftops add up to the same area as the biggest solar farm – but they could generate electricity where it’s most used to keep the lights on during disasters.
A blustery August saw gas generation more than halve compared with 2023.
The European Union gave South Africa grants of €32 million to set up a green hydrogen industry. But the real cost to do this will be €20 billion. More funds are needed.
Mining operations can damage both communities and the natural world. Yet, the demand for critical minerals to supply the renewable energy industry is rising.
