Electric cars are not enough to reduce emissions, we need alternative fuels



Electric cars are often regarded as one of the great hopes for combating climate change. With new models in the showrooms, major automakers converting to an electric future, and a small but growing number of consumers looking to convert gas consumers, electric vehicles seem to offer a possibility with only minor changes to our way of life to reduce carbon dioxide emissions. 19659002] Nevertheless, there is a risk that the attachment to electric cars leaves a large blind spot. Electrification would be very expensive for the heavy trucks transporting goods across continents, or is currently technically prohibitive for long distance transport for energy in the transport sector compared to 28 percent for heavy road vehicles, 1

0 percent for the air, 9 percent for the sea and 2 percent for the rail.

Put simply, the current focus on passenger car electrification – although desirable – only makes up part of the answer. For most other segments, fuels will be needed in the foreseeable future. And even for cars, electric vehicles are not a panacea.

The unfortunate truth is that battery-buffered electric vehicles (BEVs) can not solve the so-called "100-EJ problem". Demand for transportation services is expected to rise dramatically in the coming decades. The International Energy Agency (IEA) therefore believes that we need to significantly reduce the energy consumption of each vehicle in order to keep the overall global energy demand in the transport sector by 2050 at a level of currently 100 exajoules (EJ). More than half Of these 100 EJ are still expected to come from petroleum products, and by that time the share of light commercial vehicles in energy demand in the transport sector is expected to fall from 50 to 34 percent.
