Do we get what the planet is telling us? | rationaldebate

It’s been an important few weeks for the planet. We have had the most recent report from the IPCC. It makes salutary reading for policymakers and for each of us individually. At the same time, at the very same time unbelievably, the UK has given the go-ahead for fracking in Lancashire against considerable public protest and against the wishes of the local authority concerned.

Democracy also has…

Kenya goes all out for renewable energy

Kenya has taken less than a decade to make giant strides in its energy sector. Key to this are two iconic renewable energy projects that have benefited from the decisive support of the African Development Bank: Turkana Wind Farm and Menengai Geothermal Power Station.

The figures speak for themselves – the nationwide electrification rate in Kenya has leapt from 28% in 2013 to more than 60% in…

NantEnergy’s zinc-air battery could power Africa’s homes — Quartz Africa

By Yomi Kazeem

One key to making electricity more efficient across the world is figuring out power storage. In recent years, lithium-ion batteries have overtaken lead-acid batteries as the industry-wide standard. But that might be set to change thanks to a new milestone in power storage innovation: zinc-air batteries

NantEnergy, a US energy company, has announced the development of a…

Solar energy is becoming more and more popular as prices drop, yet a home powered by the Sun isn’t free from the grid because solar panels don’t store energy for later. Now, researchers have refined a device that can both harvest andstore solar energy, and they hope it will one day bring…

Unlimited Energy- Are Oceans the Key to Future? | Curiosity Alive

Are oceans the key to future?

We live on this beautiful blue planet called Earth made of 3/4th of oceans, and yet we use mostly energy sources largely obtained from the remaining ¼th lands and from deep buried wells of natural gas and crude oil. Oceans are there from millions of years on earth, and they will till the end of earth, so that means free energy for all the people on Earth, right?

It’s gravity, man!

OK, this is a good one.

What’s the biggest unsolved problem in renewable energy?  It’s energy storage. Solar and wind power are great, but we need smooth, continuous supply, even when the wind is quiet and at night.  Battery technology continues to improve, but remains expensive and often fragile.

Batteries generally use electrochemical processes to absorb…

Switching to Green Electricity – The Carbon Negative Family

By CATHERINE GRACEY

One of the fastest and easiest ways that we can reduce our emissions is by being aware of the electricity that we use and where it comes from. As a nation, Australia is heavily reliant on fossil fuels for electricity, which provided 83.7% of our electricity in 2016 compared to renewable sources at 16.3%. We live in Victoria, which isn’t exactly dazzling in converting to…

An Update On The World Embracing Renewable Energies – Enjoyneer

Out with the old, in with the renewable! Renewables are the future, and the world is already embracing them in a big way thanks to their potential to quite literally change the future. Not convinced? Just look at a few of the big numbers to see what we mean:

  • • In 2016, renewables made up 17% of all energy consumed in the EU
  • • By 2020, that number will likely be 20%
  • • In Austria, annual renewable…
