As energy systems electrify, it will become increasingly important to measure renewables as a portion of overall power generation to fully understand how fast economies are decarbonising.
Car markets in most developing countries are fed with used exports from Europe, the US and Japan. How these markets develop will influence how fast Africa can move from fossil fuel to electric vehicles.
CO2 emission limits for trucks have come into force much later than for cars in the EU, and it is still unclear what technology could be used to reduce their climate impact.
Heat pumps provide energy-efficient heating and cooling and are one of the most effective technologies available to decarbonise buildings.
Using electric trucks for urban deliveries can reduce greenhouse gas emissions and improve air quality, but key to keeping costs down is knowing when to charge, says Julia Hildermeier from the Regulatory Assistance Project.
Massive hydropower projects are frequently criticised for causing more harm than good. What role should they really be playing in the clean energy transition?
Technology and some visionary thinking can make clean energy affordable for everyone, says Octopus founder Greg Jackson.
The UK government’s Ten Point Plan for a green industrial revolution sketches out a map to a net-zero economy, but much still needs to be filled in.
Off-grid solar only represents a tiny percentage of renewable energy, but it's vital for the poorest households in developing countries. This success story risks being jeopardised by the Covid pandemic.
G20 leaders need to ditch voluntary commitments and set clear, measurable targets for clean energy access when they meet later this month.
US clean energy stocks appear to have priced in a Biden win. But with policy details hazy and progress uncertain, the sector isn’t home and dry.
The massive increase in demand for lithium-ion batteries threatens to create supply chains that are fragile as well as socially and environmentally unsustainable. Governments and the private sector are taking action.
Clean energy entrepreneur Danny Kennedy believes California’s Salton Sea geothermal field could be “a green, home-grown lithium resource” unlocking transport electrification.
