Green energy is the future, but fossil fuels are still needed

The Astana World Expo has offered a glimpse of the drive towards a fossil fuel free future, which is moving faster than many analysts predicted.

The theme of the Astana Expo is Future Energy. Companies and countries around the world are participating to sell their vision of a cleaner, more environmental-friendly future. Still, there's modest space for a fossil-fuel future which focuses on renewables.

The World Petroleum Association believes fossil fuels will still be needed in the long-term future, as the organization’s President Joseph Tott said: "A complete replacement needs a long, long, long time. It's not a sudden switch to renewable. Many expect that in 30 years time, still oil and gas will be a very significant part of the energy mix. We have to think in terms of energy mix that we think from country to country, region to region.”

Humanity's reliance on fossil fuels is killing the planet. However, judging by Kazakhstan's Expo crystal ball - that reliance still exists.
