The growth in clean technology has coincided with another long-term trend – the worldwide rise in urbanisation. Three years ago the United Nations (UN) estimated around 54% of the world’s population lived in a city. By 2050, this figure is projected to grow to 66%.
This change, along with climate change itself, heralds a major infrastructure challenge. The cities of the future will need to be powered in a very different way.
Instead of running transport and heating networks on thermal energies, like coal, oil and gas, many, including the UN, see the most viable solution being electrification. And renewable energy is central to this.
