Five Grand
Challenges

Most people associate climate change with power production and the burning of fossil fuels. Renewables are getting cheaper and many countries are committing to rely more on them and less on fossil fuels for their electricity needs. De-carbonising the way we generate electricity remains a fundamental part of the solution.

However, making electricity is responsible for only 25% of all greenhouse gas emissions each year. So even if we could generate all the electricity we need without emitting a single molecule of greenhouse gas we would cut total emissions by just a quarter.

To prevent the worst effects of climate change, we need to get to zero net greenhouse gas emissions in every sector of the economy within 50 years. That means dealing with electricity, and the other 75% too.

Five Grand Challenges

Renewables are getting cheaper and many countries are committing to rely more on them and less on fossil fuels for their electricity needs. De-carbonising the way we generate electricity remains a fundamental part of the solution.

Bill Gates has outlined his ‘Grand Challenges’ in stopping climate change and describes them as five main categories. He has set up a global investment fund ‘Breakthrough Energy’ who are looking for projects that solve and support the transition to a zero-carbon future.

The final 10% is a sixth, miscellaneous category that includes things like the energy it takes to extract oil and gas.
