Natural gas is the cleanest fossil fuel. For Russia, the world’s most important producer, natural gas is first and foremost a ticket back to geopolitical power.
Oil will remain the world’s top energy source for decades to come, but an imminent decline in oil production could send prices soaring. What sounds like a dream come true for climate activists - the slow end of the Oil Age - could be a time wrought with tensions.
Coal is the world’s number one source of electricity. Unfortunately, it is also the number one energy source of carbon dioxide emissions.

Every day, the Earth receives more energy from the sun than mankind uses in a year. Still, solar energy remains a tiny sliver in the global energy mix.
Dams are the most common way of generating energy from the flow of water. Now investors are trying to tap into the massive energy resources of ocean waves and tides.
