The following conclusions can be drawn:
- Fossil fuels contribute today the major part of the energy consumed by mankind.
- In future the fossil fuels will not suffice, so alternative methods have to be utilised.
- Currently, the burning of fossil fuels emits large quantities of CO2. The amount of CO2 in the atmosphere is on the increase. This can be measured and is very well documented. The consequences of this are a point of contention. But the risk of doing nothing or too little is alarming. Any means to reduce the use of fossil fuels as soon as possible is extremely urgent.
- Electric generation is causing the biggest CO2 emissions but as generation is produced in big units it is also “easiest” to fix. One way is to capture and store the CO2. Another way is to replace this generation by hydro, wind and solar, which produce less CO2 and transmit the power over long distances to the consumers by HVDC.
- Transportation is the second biggest emitter of CO2. To reduce their use of fossil fuels is also urgent. Not only from the perspective that oil will probably be the first fossil fuel to pass the peak, but also from the perspective of the immediate environmental impact of CO2 emissions. Here a transition to electric feeding would appear to be the best solution.
