The global transition to clean energy – explained in 12 charts

Matias Prieto — Mon, 24 Jun 2019 06:06:59 +0000

A report released by Renewable Energy Policy Network for the 21st Century (REN21) goes into that question in considerable detail. The Renewables Global Status Report (GSR) digs into the growth rates of various energy sources, the flows of clean energy investment, and the world’s progress on its sustainability goals. But first, we are still moving […]

How to Build a Mini Hydroelectric Generator from Washing Machine Parts

Matias Prieto — Mon, 19 Nov 2018 14:38:43 +0000

In this video we will see how an old washing machine is converted into a little hydroelectric generator for powering an off the grid house. Essentially, what he does is attaching a Pelton wheel to the shaft, diverting some of the water through a pipe and the difference in height between the water intake and […]

Estream, a portable water turbine to power electronic devices

Mila Luleva — Tue, 16 Aug 2016 20:58:28 +0000

Estream is the latest technology that provides portable power for electronic devices. It is hydro-turbine that uses the force of flowing river streams. Staying connected at all times is now more important than ever. Only a decade ago a lack of a mobile phone or reception (or Wi-Fi for this matter) was not really a big deal. […]

Hydroelectric Dams Disturbing to Wildlife, Study Finds

Courtney Lepping — Tue, 31 May 2016 18:42:17 +0000

Hydroelectric dams were recently recognized to threaten a number of species on reservoir islands. Popular around the world, hydroelectric dams were discovered to have a reduction in animal and plant life after flooding. The dams have been said to protect species from hunting and deforestation, but research has shown a disturbing trend. After careful inspection […]

UC Professor’s Device Produces Energy from Evaporating Water

Mila Luleva — Mon, 28 Dec 2015 17:46:29 +0000

Scientists from Columbia University have built a device that generates electricity from evaporating water. Over the years people have found many different ways to generate renewable energy, some more conventional than others. Most of these means (with exception of solar) involve harnessing of the energy generated through some sort of motion- either wind, water, or […]

Roadblocks to Hydro Power Generation in Bhutan

Annika Tostengard — Sat, 12 Dec 2015 15:50:17 +0000

Bhutan is a small country, located northeast of India. While small, the country has the potential to generate a massive amount of hydro power, since it is home to mountainous terrain brimming with fast-flowing rivers. The area could generate up to 30,000 MW of power, though it is estimated that, given the limits of technology, 24,000 MW […]

Floating Sea Wall Makes Energy from Rivers

Samantha Joe — Thu, 10 Dec 2015 20:43:42 +0000

Waterstudio, led by Koen Olthuis, is a Dutch firm that explores solutions in urban planning and research as it relates to water. One of their concepts is a floating sea wall, named The Parthenon. The Parthenon serves multiple purposes: it slows water as it pushes into a harbor, and harvests the energy that water generates. […]

South-North Water Transfer Project in China

Anthony Petrolo — Sun, 31 May 2015 04:25:26 +0000

One of the fastest-growing developing mega-economies in the world is striking more environmental hurdles than expected. This time, it is in regards to water security, rather than atmospheric pollution. Some key environmental problems that are becoming more evident (or beginning to manifest) include soil degradation, over-extraction and pollution of (both surface and ground) water sources, […]

Blue Freedom – the Smallest Portable Hydropower Plant

Mila Luleva — Wed, 25 Mar 2015 11:24:23 +0000

A new tiny portable hydropower plant offers a super fast alternative to solar and kinetic energy powered back-up chargers. Back-up power devices have grown in popularity over the past few years, as the dependence on new smart phone and electronic technologies has increased rapidly. Everyone “needs” to be always connected and aware of what is […]
