renewables

Unless renewables become cheap enough that substantial carbon deposits are left underground for a very long time, if not forever, the planet will likely be exposed to potentially catastrophic climate risks.

Technological innovations have unleashed the power of renewables such as wind, hydro, solar, and geothermal .

Renewables account for only a small share of global primary energy consumption, which is still dominated by fossil fuels—30% each for coal and oil, 25% for natural gas.

Progress in the development of renewables could be fragile, however, if fossil fuel prices remain low for long.

Even Africa and the Middle East, home to economies that are heavily dependent on fossil fuel exports, have enormous potential to develop renewables.

He and other scientists say there are basically two options to replacing fossil fuels: generating energy with renewables or embracing nuclear power.

Technological innovations have unleashed the power of renewables such as wind, hydro, solar, and geothermal (地热).

Some experts believe printers could use hydrocolloids from plentiful renewables like algae and grass to replace the familiar ingredients.

But increasingly the story is about the plummeting prices of renewables, especially wind and solar.

The move to renewables is picking up momentum around the world: They now account for more than half of new power sources going on line.

While there's a long way to go, the trend lines for renewables are spiking.
