The automotive industry is on the brink of a major upheaval due to the arrival of electric vehicles. Not only cars, also delivery vans, trucks, buses – you name it. After the automotive industry tried to pretend for years that nothing serious was going on, it is now increasingly clear that change is unavoidable, and may come much faster than many think. There is presently a lot of arguing and sweating in the board rooms. Some will take right decisions, some will take wrong. Some well-known car companies may survive and prosper – others may disappear ingloriously in the coming…

Electric cars are too expensive

Written by
Electric vehicles are presently ridiculously expensive. Could be the cost of the battery, couldn’t it? That is only part of the explanation. The other is scale: the production volume is too low to secure economies of scale. And to this comes a lack of competition: existing car producers are not really interested in selling quantities, as they will cannibalize their own profitable traditional car business. The answer is regulation and more competition. Not more subsidies.

We have just seen a flurry of new reports on Climate Change, and they are not funny reading. Before we fall into gloom and accept that the end is nigh, the good news is that with what we already know and the instruments we have at hand, it is absolutely within our reach to avoid the worst climate change scenarios, and the cost is absolutely not scaring. But it needs bold and determined policies and willingness to take risks. The lack of capacity for this is the biggest risk we are facing.

The cost of solar energy has plunged in recent years, and solar panels are now dirt cheap. We have just installed a 46 kW solar roof top system here in Leon, Nicaragua, which produces energy at 7.5 cents of a US dollar – that is around a third of what the electricity company charges us. So there is no excuse for continuing contributing to global warming. The energy revolution is here, right now.

The Paris summit ended with an agreement, fortunately. Not good enough to save our grandchildren from climate disaster, but at least a beginning, which we hopefully will be able to build upon. Apart from the climate change deniers, who live in their own claustrophobic world, much of the disagreement is about justice: which are the countries to blame, and which should clean up their acts first? The Paris summit tried to avoid the question of justice and convince us that we all have to contribute, including the developing countries. And the developing countries seem to have gruntingly accepted that.

As oil prices have plummeted, they have overshadowed the other important reality: renewable energy prices are also falling. And contrary to oil prices, the fall will continue in the future. So renewables are becoming a viable and profitable alternative for electricity generation, helping the world to get off its dependency on fossil fuels. But what about cars? They are intimately linked to fossil fuels, or – if need be – biofuels, to make the internal combustion engine work. Worldwide, transport is actually responsible for around 27% of all energy consumption, and 63% of oil consumption. So is there any future…
