De 20 beste ideeën om de klimaatcrisis te bestrijden
De krant The Guardian en het Manchester International Festival stelden een internationaal expertpanel samen over klimaatverandering. Het panel moest meer bepaald op zoek naar ideeën om de klimaatcrisis te bestrijden.
Dit is een top 10 en een top 20 van de beste ideeën:
The panel's top ten
Gerry Wolff explains how concentrating solar power in deserts could supply enough electricity to power the whole of Europe.
Switching from uranium to thorium as our primarily nuclear fuel could lead to cheaper, safer and more sustainable nuclear power.
If affordable carbon capture and storage technologies can be developed, the prospect is there for "carbon negative" power plants that burn a mix of coal and wood.
Domestic fuels cells are super-efficient mini power stations that can efficiently and cheaply provide electricity and hot water.
Turning crop wastes and other biomass into charcoal and spreading it on tropical soils can sequester carbon and boost crop productivity.
Marine turbines are like underwater windmills than can extract energy from fast-flowing tides or deep ocean currents.
Grazing cattle in a way that imitates the movements of wild herds could lock huge quantities of CO2 into the world's dry soils.
Simple and inexpensive biomass cooking stoves can slash emissions, save forests and avoid lung disease.
Global investment in family planning and female education could slow down global population growth, reducing future emissions and tackling climate change vulnerability.
Enhanced geothermal systems, or 'hot rocks', can be exploited in a larger number of locations and operate 24 hours a day.
The 10 runners up
Backed by the government, 'energy bonds' would allow individuals and institutional investors to finance a renewable energy revolution.
Knowledge and awareness of climate change isn't enough to influence low-carbon lifestyle changes; people need to be engaged on a emotional level.
Giant plastic 'stomachs' in the sea could be used to digest seaweed farmed at the ocean surface, converting it into CO2 for burial and methane for cooking and heating.
Carbon dioxide generated by power stations can be converted into methanol and used to generate electricity or fuel cars.
Putting lime into the oceans has the potential to decrease ocean acidity and reduce atmospheric CO2 levels.
Schemes for leasing super-lightweight low-carbon cars could help slash the emissions of the transport sector.
Solar photovoltaic energy reduces emissions both directly and indirectly – and it can make an ideal long-term investment vehicle, according to its advocates.
Rethinking economics to reduce consumption and emissions and boost life satisfaction.
Ships that spray minute water droplets into the sky could increase cloud cover and reflect sunlight away from the earth.
