The Yarlung Tansgpo / Brahmaputra dam shows we often don’t know how to deal with rivers that cross national borders.
Energy storage really is the special sauce that makes renewables work anytime, anywhere – and everywhere. This makes the most of the existing electricity network, including transmission lines.
The good news is that New Zealand is on track to meet electricity demand with renewable generation by 2030. The less good news is that winter price spikes are still likely.
If Africa built only all the renewable power plants it has already planned, this would be enough to generate 76% of all electricity needed on the continent by 2040.
Communities along the bank of the dam have been victims of injustice since the early 1960s.
To address Africa’s heavy dependence on fossil fuels and hydropower, there is a need for investment in renewable energy sources like wind and solar.
Experts say greater use of renewable energy via solar photovoltaic and hydro power is the best route to universal access to electricity in Togo.
Proper dam management can help check flooding in Nigeria.
The project violates colonial-era water rights but promises cheap and clean power to East Africa.
Solar PV is the future of energy in Indonesia. Indonesia has vast solar energy potential, far larger than all other energy sources combined.
Dam politics have resurfaced in Africa as the continent’s urban population grows.
While it’s impossible to stop all extraction of fossil fuels now, renewable sources are already generating 25% of global electricity demand now and their contribution continues to grow.
