Helsinki Blasted Out An Underground Lake To Water-Cool Its Buildings

If you’ve visited Helsinki, you’ve probably spent time in its leafy Esplanade Park at the center of the city.

Pouring Saltwater Over Graphene Generates Electricity

A team of Chinese scientists did an impossible-sounding thing. They created electricity simply by dragging a droplet of saltwater across a layer of graphene. No big fires, no greenhouse gases, no fuss. They created energy with just a miracle material and one of the most plentiful substances on Earth.

Moss-Covered Table Uses Photosynthesis To Power An FM Radio

As an electricity source, what could be greener than plants? That’s the idea behind this rig, the world’s first system that powers an FM radio using nothing more than the photosynthetic powers of moss. And creators Fabienne Felder and Dr Paolo Bombelli are just getting started.

The Batteries Of The Future Could Be Powered By Rhubarb

Building the perfect battery is a hard problem. Batteries either too inefficient or too expensive or too unstable to power the renewable gadgets of the future. But a team of Harvard scientists just built a new kind of battery with a molecule found in food, and it could solve these problems.

Can Wave Energy Really Power Australia's Future?

CSIRO recently announced that energy from the ocean — also known as wave energy — could supply 11% of Australia’s demand by 2050. That is enough to power a city the size of Melbourne. It is a bold claim, but it’s time for Australia to look at the sea differently.

Apple's Data Centres Will Be Powered Entirely By Renewable Energy

Greenpeace has been on the offensive against Apple this week, blasting the company for sourcing the power for its energy-intensive data centres from coal power plants. Today, Apple fired back with some remarkable facts, claiming it’s a clean and renewable energy superstar.

Super Powerful Wind Turbine Taller Than Washington Monument

Wind blows. And if there’s energy (and money) to be made from this fact of life, we may as well take advantage of it, right? That’s what Vestas is doing – and they’re using the V164-7.0 MW, a massive 187m wind turbine, to do it.

80% Of Global Power Could Come From Renewable Sources By 2050

Mark it down in the diaries, folks… Provided the world doesn’t come to a cataclysmic end next year, the UN believes that humankind can get 80 per cent of its energy from renewable sources by the year 2050.
