Quest for renewable energy continues: EXPO 2017 Astana Updated: 2017-09-11 21:22:55 KST

A Lightbulb that doesn't get hot.
Using graphene, the world's most conductive material, almost unknown before 2004, the lightbulb is at least 10% more energy efficient and 10 times brighter than conventional bulbs.
An algae-powered house.
Micro-algae breeds within the building's shell, using photosynthesis and solar energy to produce biomass and electricity.

"It has special algae technology plants growing in special glass, using sunlight and water to produce electricity and heat for 15 apartments in Hamburg."

"It's more than just wind turbines and solar panels. Here in Kazakhstan's capital city of Astana, 115 countries are showcasing their latest clean energy technology under the Expo's theme of "future energy."

What makes the Astana expo even more special is that it's interactive.
As children rock up and down the seesaw, water pours back and forth through blades, generating energy to turn on a light.
Using smart pads, visitors can learn about the concept and application of different kinds of renewable energy at the Korea Pavilion, which was visited by close to 6000 people a day.

The host country Kazakhstan's exhibit displays every kind of energy, from hydro power to the creation of the universe.

A fifth of the former Soviet country's economy is based on its oil reserves, which account for 60% of its exports.
But with oil prices down by at least half since 2014, and the world turning its focus to sustainable energy, Kazakhstan hopes to lead the way in pushing countries to come up with cleaner energy.

"One of the achievements made at this expo is that we signed 46 energy investment-related agreements. As a member of the Paris Accord, our goal is to draw 50 percent of our energy from renewables by 2050."

The three-month-long expo has come to a close, but it also marks a beginning as countries, visitors, and investors look toward the future of energy.
