Iceland is a country that depends on Denmark, is populated by less than 400,000 people and has a very particular geography. It is full of volcanoes, basalt (material of volcanic origin) and geothermal springs.
Since the land is very poor, they have sharpened their intelligence and have made good use of their natural resources. The heating of 85% of their houses is of geothermal origin, and 70% of the electricity they generate is of non-polluting origin (hydroelectric or geothermal).
That makes their pollution levels very low and they have a goal of becoming carbon neutral by 2040, several decades earlier than other countries. And logically their goal is to do it with the resources they have, and with a little technological help.
Apart from being able to ensure that all the electricity they generate is non-polluting, they have industrial and transport processes (cars, ships and planes) that generate pollution, and they intend to eliminate it in two ways.
On the one hand, using non-polluting synthetic fuels, which although they are more expensive to obtain, do not dirty our atmosphere, and allow them to continue using the current vehicles (cars, boats, etc…) necessary to continue operating, since Iceland is a country that needs to import everything, because many type of materials they need are transported from afar.
And on the other hand, carrying out processes of sequestration of CO2 from the atmosphere, and mixing it with the dust of its basaltic rocks, and later being buried in the ground.
Both processes are more expensive than those currently available, but do not generate additional pollution. And this is the most important part to consider for the future.
The new electric cars have the positive side that they consume electricity and do not pollute when they work, but they need rare, scarce and expensive metals for their construction.
A pre-built used car, if we can get it to run on non-polluting synthetic gasoline, would be a big step in the right direction.
The need to avoid polluting our atmosphere can be resolved in different ways, and we should not disregard any of them. Everyone contributes a little.
It seems that our friends in Iceland have it very clear, and I'm glad for that.
