Subsidizing Coal, Nuclear Could Drive Customers Off-Grid

Renewable Energy World - Wed, 11/15/2017 - 17:52

Within the next month, energy watchers expect the Federal Energy Regulatory Commission to act on an order from Energy Secretary Rick Perry that would create new pricing rules for certain power plants that can store fuel on site to support grid resilience. This initiative seeks to protect coal-fired and nuclear power plants that are struggling to compete with cheaper energy sources.

Solar Companies Scramble to Find a Critical Raw Material

Renewable Energy World - Wed, 11/15/2017 - 17:38

Solar manufacturers are being battered by higher costs and smaller margins after an unexpected shortage of a critical raw material. Prices of polysilicon, the main component of photovoltaic cells, spiked as much as 35 percent in the past four months after environmental regulators in China shut down several factories.

An Inconvenient Sequel – the science, history, and politics of climate change | John Abraham

Guardian - Renewable Energy - Wed, 11/15/2017 - 11:00

Al Gore’s new film is worth watching

Al Gore’s new movie ‘An Inconvenient Sequel’ is, in some ways, similar to his groundbreaking Inconvenient Truth project, but different in other ways. Those key differences are why I recommend you watch it.

This movie successfully accomplishes a number of interweaving tasks. First, it gives some of the science of climate change. Gore gets his science right. I remember his first movie, which I thought was more steeped in science and data than this one, so based on my recollection this new picture is somewhat abbreviated. That’s a good thing because the science is settled on climate change. That is, the science is settled that humans are causing current climatic changes and the science is settled that we are observing these changes throughout the natural world.

Why Solar Microgrids Are Not a Cure-All for Puerto Rico’s Power Woes

Renewable Energy World - Tue, 11/14/2017 - 16:27

In addition to its many other devastating human consequences, Hurricane Maria left the island of Puerto Rico with its power grid in ruins. Power was knocked out throughout the island, with an estimated 80 percent of its transmission and distribution wires incapacitated. When hospitals and other critical users could not get backup power and water supplies ran low, an extended outage became a humanitarian crisis that has yet to be resolved.

Where Does CSP Fit on the US Power Grid?

Renewable Energy World - Tue, 11/14/2017 - 16:00

Every day our power needs fluctuate, causing grid operators to make quick decisions to balance the U.S. grid. This can happen on hot summer days when people are turning on their air conditioners or in the middle of winter when they crank up the heat. Either way, grid operators must find a way to meet rapid spikes in energy demands.

It’s true, wind turbines are monstrous. But I have learned to love them | Alice O’Keeffe

Guardian - Renewable Energy - Sat, 11/11/2017 - 06:00
At first I resented the way they blocked the view. But now the towers look like part of a brighter future

Over the last few months I have been watching with mixed feelings as the Rampion wind farm emerges like a great monster from the sea off Brighton beach. It has happened so quickly: one morning in the early summer a few small grey stumps appeared on the previously flat horizon. Only weeks later, the first turbines were up, instantly giving the familiar sea view a new, industrial edge. Since then more and more have appeared, row upon row of them. Though they are eight miles offshore, they dominate the view from the beach now, and create strange optical illusions; in some weathers they look close, and in others very far away. Occasionally, on a seemingly clear day, they inexplicably disappear from view.

Over the summer I mourned the glorious, uninterrupted horizons that used to beckon

US switches focus of its Bonn event from clean energy to fossil fuels

Guardian - Renewable Energy - Fri, 11/10/2017 - 16:41

One of US’s only public events, originally billed as promoting clean energy, has since been changed to favour coal and nuclear power

The US has changed the focus of one of its few public events at the Bonn climate talks to emphasise coal and nuclear power, in a sign of the Trump administration’s goals at the talks.

An event next Monday, opening the second week of the ongoing UN negotiations, was originally billed as promoting clean energy. However, it has since been changed to emphasise coal and nuclear power.
