Renewable energy

Why our approach to World Forests Day is a threat to forests

Souparna Lahiri writes: How will forests provide for such high energy demands being put on them, especially in the name of renewables? In the Global South, there’s a rise in monoculture tree plantations for biofuels, or wood. Biofuel plantations have already caused the clearing of rainforests and threatened animals and humans that depend on them.

How renewable energy advocates are hurting the climate cause

Paul McDivitt writes: Making wind and solar seem like they’re doing better than they really are could come back to bite proponents —and the climate. If people think we are about to replace fossil fuels with renewables, they will be less likely to demand new policies and take actions to lower their own carbon footprints.

Gail Tverberg: The “wind and solar will save us” delusion

Somehow, most people seem to believe that our economy of 7.5 billion people can get along with a very short list of energy supplies. Given climate change, this short list cannot include fossil fuels, but we believe Wind and Solar can save us. Unfortunately, a transition to such alternative fuels can’t really work. Here’s why.

The draft national electricity plan paints rosy picture of power scenario

Every five years, the Central Electricity Authority prepares a National Electricity Plan. Last December, the CEA released draft of third NEP for 2017-2022 seeking comments from various stakeholders. Some of its conclusions, like ‘close to zero energy demand deficit’, may sound like music to power starved India but also raises serious questions about its authenticity.

Tribute: T. Hanumantha Rao, champion of water management alternatives

T. Hanumantha Rao, irrigation engineering expert and the brain behind a participative method of water management based on his ‘Four Waters’ concept, passed away on Sunday. The Four Waters concept, explained in this video, brought rich benefits to Rajasthan, where even drought-affected areas improved over the years. Several other states are actively pursuing his recommendations.

New study says solar panels have repaid their fossil fuel debt

Phys.org reports: The climate friendly electricity generated by solar panels in the past 40 years has all but cancelled out the polluting energy used to produce them, a study said Tuesday. Indeed, by some calculations, the so-called “break-even point” between dirty energy input and clean output may already have arrived, researchers in the Netherlands reported.

The mineral pie is shrinking, and most of what’s left is in the sky

Ugo Bardi writes on Cassandra’s Legacy: The essence of propaganda, as it is well-known, is not so much telling lies, but presenting only one aspect of the truth. That’s true also for the depletion debate. Saying that a certain resource will last decades, centuries, or more is not a lie, but not the truth, either.

47 of the world’s poorest countries are aiming to hit 100% renewable energy

As the world’s leading superpowers struggle to make the transition from fossil-based energy systems, 47 of the world’s poorest nations have pledged to skip fossil fuels altogether and jump straight to using 100 percent renewable energy instead. The ambitious goal was laid out during the final day of the UN Climate Change Conference in Morocco.

The hydropower paradox: is this energy as clean as it seems?

Hydropower is a significant source of greenhouse gas emissions: a new study shows that the world’s hydroelectric dams are responsible for as much methane emissions as Canada. The study finds that methane, which is at least 34 times more potent than carbon dioxide, makes up 80% of the emissions from water reservoirs created by dams.

Is renewable energy really environmentally friendly?

Robin Delobel writes: The issue is rarely raised, but renewable energies have a heavy environmental impact when the total production chain and overall product life-cycle is taken into account– particularly, the stage of mining the metals needed in their production. In addition, chemical products used in the mining operations often lead to severe long-term pollution.

Why is India holding out on the Paris Climate Agreement?

Global Risk Insights reports: Recent developments suggest that India has been seeking to leverage its ratification of the Paris Agreement. Specifically, the Modi Government has claimed it will only be able to meet emissions reduction targets if it rapidly expands its capacity to produce nuclear energy, which would be difficult to achieve without NSG membership. Global

India charts a roadmap to achieve ambitious solar targets

Katherine Ross reports: Last month’s release of India’s ambitious year-on-year solar energy capacity targets chart a roadmap for achieving the country’s 2022 goal. This sequence of yearly targets—as opposed to an assumed growth trend between current capacity and targeted capacity—shows that India is making concerted plans to reach its goals announced at the Paris talks.

The end of the fossil fuel era and Hyderabad’s energy future

The revised version of a talk given by Soujanya Mantravadi at the Future of Energy for Hyderabad workshop held at La Makaan, Hyderabad on 24. 07. 2016, organized by Ecologise Hyderabad. It explores the implications of the end of the fossil fuel era and ways in which residents of Hyderabad can start preparing for it.

Why the world’s fossil fuel output will peak by 2025

Dennis Coyne writes: I expect World Fossil fuel output to peak in 2025. If the World economy continues to grow, a gap between Energy produced (including non-fossil fuels) and the demand for Energy will grow. If the gap is not filled by growth in non-fossil fuel energy demand will reduce due to reduced economic growth.

The climate crisis is already here – but no one’s telling us

George Monbiot writes: If humanity fails to prevent climate breakdown, the industry that bears the greatest responsibility is not transport, farming, gas, oil or even coal. All of them can behave as they do, shunting us towards systemic collapse. The problem begins with the industry that, wittingly or otherwise, grants them this licence: the media.

Ecologise Hyderabad: Energy Workshop Report

Soujanya Mantravadi writes: The workshop was attended by 32 participants. Organised by three members of the Ecologise group and five resource people, the programme was intended to send out a strong message that the energy aspects of the city is goes beyond electricity. The workshop witnessed elaborate and edifying discussions between the participants and speakers.

Clean energy won’t save us – only a new economic system can do that

Jason Hickel writes: When it comes to climate change, the problem is not just the type of energy we are using, it is what we’re doing with it. What would we do with 100% clean energy? Exactly what we are currently doing with fossil fuels: raze more forests, build more meat farms, expand industrial agriculture.

Video: This wind turbine costs as much as an iPhone, powers an entire house

Avant Garde Innovations, founded by siblings Arun and Anoop George from Kerala, has come up with a low-cost wind turbine that can generate enough electricity to power an entire house for a lifetime. The size of a ceiling fan, this wind turbine can generate 5 kWh/kW per day— with just a one-time cost of US$750.

Collision course: The incompatibility of India’s coal and renewable strategies

CoalSwarm’s new report details how India has a total of 243 GW of coal plants under development, threatening to derail its renewable energy ambitions, leading to either locked-out renewables or stranded coal plants. It would push the country towards more expensive and underutilized coal plants at the expense of lower cost and cleaner renewable energy.

How industrial civilisation is (literally) built on a foundation with an expiry date

Chris Martenson writes: The main issue is simple: putting in steel reinforcing bars lowers the cost and weight of installing reinforced concrete, but at the severe expense of reducing its lifespan. In other words, literally everything you see today that’s made of concrete will need to be replaced within a hundred years of its installation.
