Can we live without fossil fuel?
Eighty per cent of our energy comes from natural gas, oil and coal. We need all of our current energy sources. Here’s one example why a no-fossil-fuel approach is absolutely unrealistic. A natural gas turbine the size of a typical residential house can supply electricity for 75,000 homes.
What are two ways to turn a turbine to generate electricity without using fossil fuels?
By combining wind and solar and geothermal and hydroelectric, you can match the power demand. And if you oversize the grid, when you’re producing extra electricity you use it to produce hydrogen [for fuel-cell vehicles and ships as well as some district heating and industrial processes].
What happens if there is no fossil fuels?
Without fossil fuel, essential items such as masks and PPE are unable to reach to other countries in time. Large-scale international trade would shut down. Commuter transportation could transit to electric rail or electric cars quickly.
How much oil is left in the world?
The Organization for Petroleum Exporting Countries reports that there are 1.5 trillion barrels of crude oil reserves left in the world. These are proven reserves that are still capable of being extracted by commercial drilling.
