The Coal Business Is Dying – It can’t come soon enough

Posted on by

This is not the point of the article but it IS my point. If most mammals, like us, are going to survive then we are going to have to leave all of the carbon that we can in the ground. By the way natural gas is no “bridge” to the future. Methane is a lot more potent green house gas. It is carbon that must be left in the ground too. So expect the natural gas companies to follow suit. The sooner the better.

The largest U.S. coal company just filed for bankruptcy

Peabody Energy, the world’s largest private-sector coal producer, filed for bankruptcy on Wednesday in a U.S. court, citing “unprecedented” industry pressures and a sharp decline in the price of coal.

The company said it will continue to operate while in bankruptcy, while working to reduce debt and improve cash flow.

“Peabody has a new management team, outstanding workforce, unmatched asset base and strong underlying operational performance that represent a key driver in the company’s future success,” CEO Glenn Kellow said in a statement announcing the Chapter 11 filing.

In addition to plummeting coal prices, the company cited weakness in China’s economy, overproduction of domestic shale gas and ongoing regulatory challenges as reasons for its declining prospects.

Wave Power – It could crash through traditional power sources

Attempts to generate electricity from tidal and river flows has had some success. People that tried to generate electricity from ocean waves have struggled. They may be on the edge of real change and I find that to be exciting.

The promise of ocean wave power has enticed, and eluded, engineers for 40 years

It’s 1974. A man stands on the Scottish coast and stares out to sea. His dark hair is ruffled by the wind, while his mind is fixed on a new, pressing problem: How can all the teeming, crashing power of the ocean be harnessed to produce electricity, in a world that has just discovered it can’t rely on cheap oil forever?

That man, and his colleagues, are still searching for the answer.

For four decades, the problem of how to create an economically viable business producing power from waves has fascinated a specialized group of engineers, many of whom are concentrated around the sea-beaten coast of Scotland. Inventors have created all sorts of strange and wonderful devices to coax energy out of the water; investors have poured millions of pounds into the effort.

The problem is arguably one of the most perplexing in energy production. And maybe, just maybe, the answer is getting closer.

Hydroelectric Power Is Under Assault – Soon it could be dead

Posted on by

As this article makes clear, we need dams. In my mind they are a trade off we can live with, and the excuse that it is just unprofitable to repair them is disgusting. Still, there are environmentalists who disagree.

One of Africa’s Biggest Dams Is Falling Apart

By

The new year has not been kind to the hydroelectric-dam industry. On January 11th, the New York Times reported that Mosul Dam, the largest such structure in Iraq, urgently requires maintenance to prevent its collapse, a disaster that could drown as many as five hundred thousand people downstream and leave a million homeless. Four days earlier, the energy minister of Zambia declared that Kariba Dam, which straddles the border between his country and Zimbabwe, holding back the world’s largest reservoir, was in “dire” condition. An unprecedented drought threatens to shut down the dam’s power production, which supplies nearly half the nation’s electricity.

The news comes as more and more of the biggest hydroelectric-dam projects around the world are being cancelled or postponed. In 2014, researchers at Oxford University reviewed the financial performance of two hundred and forty-five dams and concluded that the “construction costs of large dams are too high to yield a positive return.” Other forms of energy generation—wind, solar, and miniature hydropower units that can be installed inside irrigation canals—are becoming competitive, and they cause far less social and environmental damage. And dams are particularly ill-suited to climate change, which simultaneously requires that they be larger (to accommodate the anticipated floods) and smaller (to be cost-effective during the anticipated droughts).

The Solar Rip Off – They never tell you up front about your RECs

I know that this is part of the motive and the profit to do solar equipment deals. It would be a better model if they told you about it up front and then split the RECs with the buyer or homeowner.

The Problem With Rooftop Solar That Nobody Is Talking About

Where does the green energy from your panels really go?

—By

 

A couple of years ago, Steven Weissman, an energy lawyer at the University of California-­Berkeley, started to shop around for solar panels for his house. It seemed like an environmental no-brainer. For zero down, leading residential provider SolarCity would install panels on his roof. The company would own the equipment, and he’d buy the power it produces for less than he had been paying his electric utility. Save money, fight climate change. Sounds like a deal.

But while reading the contract, Weissman discovered the fine print that helps make that deal possible: SolarCity would also retain ownership of his system’s renewable energy credits. It’s the kind of detail your average solar customer wouldn’t notice or maybe care about. But to Weissman, it was an unexpected letdown.

To understand his hang-up, you need a bit of Electricity 101. If you have solar panels on your roof, the electrons they produce flow across the electric grid like water, following a path of least resistance. As they whiz around, electrons are impossible to track and look identical, whether they’re coming from solar panels, a coal plant, or whatever. But there is value in keeping tabs on the renewable ones, so energy wonks came up with renewable energy credits (RECs), a tradable financial instrument that corresponds to a certain amount of energy produced by a certain renewable source like solar or wind.

Coal Is Dead – Solar is the future

Coal is now the most expensive energy source in the United States. That means that it will be to expensive to mine. It also means that the worth of the mining companies will fall and their stocks will collapse. It  can’t happen soon enough for me.

A Sunny Future for Utility-Scale Solar
By John Finnigan | Bio | Published: December 28, 2015
Utility-scale solar and distributed solar both have an important role to play in reducing greenhouse emissions, and both have made great strides in the past year.
Utility-scale solar, the focus of this article, is reaching “grid parity” (i.e., cost equivalency) with traditional generation in more areas across the country.  And solar received a major boost when the federal tax incentive was recently extended through 2021. The amount of the incentive decreases over time, but the solar industry may be able to offset the lower tax incentive if costs continue to decline.  New changes in policy and technology may further boost its prospects.
Record year for utility-scale solar
Some of the world’s largest solar plants came on-line in the U.S. during the past year, such as the 550-megawatt (MW) Topaz Solar plant in San Luis Obispo County, California and the 550MW Desert Sunlight plant in Desert Center, California. Last year saw a record increase in the amount of new utility-scale solar photovoltaic generation installed – about four gigawatts (GW), a whopping 38 percent increase over 2013, and enough solar power to supply electricity to 1.2 million homes.  This number is expected to increase in 2015 when the final numbers are in.

Exelon Lied About The Viability Of Their Nukes – They will not close

They were losing money. Lay offs were coming. At least three plants were going to close. But, then not so much. Maybe they should just close them instead and invest in solar.

Clinton nuclear plant gets reprieve

Exelon won’t close facility for at least a year

By Patrick Yeagle

Despite years of unfavorable conditions, Exelon thinks next year may be different.

The company announced earlier this year it won’t close the Clinton Nuclear Power Plant, 45 miles east of Springfield, for at least another year in light of potential market reforms in Illinois. The announcement follows similar announcements for two of Exelon’s other Illinois nuclear plants. Meanwhile anti-nuclear groups are calling for the plants to begin shutting down now.

The landscape of the energy market is undergoing major changes as coal plants begin to close, thanks in large part to tightening environmental regulations and a glut of cheap natural gas. Because coal has long been one of the main fuels for electricity production in the U.S., its decline creates a vacuum for other sources of electricity to fill. While environmental groups prefer more solar, wind and hydro electricity, companies which operate nuclear power plants see an opportunity for a larger role.

In Illinois, however, nuclear power has faced a competitive disadvantage since the late 1990s due to the state’s “deregulated” energy market. Illinois law requires a separation between companies that generate electricity and those which transmit electricity to customers. (Springfield’s City Water, Light and Power is allowed to own both generation and transmission assets because it’s a municipal utility.)

Unfortunately it will be several years before we know whether it will make a dent in emissions, but as everyone says, it is a start. I am particularly excited by the concept of “ratchet” and whether it can be implemented. What do you think?

Temperature Increase

“Holding the increase in the global average temperature to well below 2°C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5°C above pre-industrial levels, recognizing that this would significantly reduce the risks and impacts of climate change.”
Justin Gillis, climate science reporter:
This agreement adopts a more ambitious target for limiting global warming than in the past by mentioning 1.5 degrees Celsius as part of the concrete goal to stay well below 2 degrees. If that were to be actually achieved, it would likely ward off some of the most severe effects of climate change. For example, although we don’t know the exact temperature, there is a trigger point at which the whole Greenland ice sheet and the West Antarctic ice sheet will melt. There is a chance that staying below 2 degrees Celsius would avoid that trigger point, and an even better chance if we stay below 1.5 degrees.

Preservation of Forests

“Parties are encouraged to take action to implement and support, including through results-based payments, the existing framework as set out in related guidance and decisions already agreed under the Convention for: policy approaches and positive incentives for activities relating to reducing emissions from deforestation and forest degradation, and the role of conservation, sustainable management of forests and enhancement of forest carbon stocks in developing countries; and alternative policy approaches, such as joint mitigation and adaptation approaches for the integral and sustainable management of forests, while reaffirming the importance of incentivizing, as appropriate, non-carbon benefits associated with such approaches.”

How Do We Fix It?

Germany Could Be a Model for How We’ll Get Power in the Future

The European nation’s energy revolution has made it a leader in replacing nukes and fossil fuels with wind and solar technology.

Hamburg knew the bombs were coming, and so the prisoners of war and forced laborers had just half a year to build the giant flak bunker. By July 1943 it was finished. A windowless cube of reinforced concrete, with seven-foot-thick walls and an even thicker roof, it towered like a medieval castle above a park near the Elbe River. The guns protruding from its four turrets would sweep Allied bombers from the sky, the Nazis promised, while tens of thousands of citizens sheltered safely behind its impenetrable walls.

Coming in at night from the North Sea just weeks after the bunker was finished, British bombers steered for the spire of St. Nikolai in the center of the city. They dropped clouds of metallic foil strips to throw off German radar and flak gunners. Targeting crowded residential neighborhoods, the bombers ignited an unquenchable firestorm that destroyed half of Hamburg and killed more than 34,000 people. Towering walls of fire created winds so strong that people were blown into the flames. Church bells clanged furiously.

The spire of St. Nikolai, which somehow survived, stands today as a mahnmal—a memorial reminding Germany of the hell brought by the Nazis. The flak bunker is another mahnmal. But now it has a new meaning: An urban development agency (IBA Hamburg) and the municipal utility (Hamburg Energie) have transformed it from a powerful reminder of Germany’s shameful past into a hopeful vision for the future.

Energy Conservation In The Developing World – Stoves can change the world

Cooking food. In the US that would not be considered either energy efficiency or even news. Yet for humans, cooking is totally necessary. In poor countries, it is a huge issue. This is good news.

India sees clean cooking as climate action that saves lives

Associated Press
By KATY DAIGLE

GANORA SHEIKH VILLAGE, India (AP) — Kamlesh feeds the flames of a crude clay cookstove with kindling, kerosene and sunbaked discs of cow dung. She breathes in the billowing smoke, as she does for hours every day. Her eyes water and sting. Her throat feels scratchy and sore.

Kamlesh is one of hundreds of millions of Indian housewives who, with the simple act of cooking family meals, fill their homes every day with deadly airborne pollutants. The constant exposure to indoor air pollution kills some 4.3 million people every year across the world — 30 percent of them in India.

The menace of cookstove pollution, which contains high concentrations of tiny particles known as black carbon, does not stop in the home. It compounds many environmental problems as well, from glacial melt to falling crop yields.

India, the world’s third-largest climate polluting nation, has spent decades encouraging cleaner cooking technologies, with limited success. Such a shift would have little impact on India’s emissions of climate-warming greenhouse gases, and many of the alternatives pollute as well.

Reliable Tidal Power – If we do this right we may avoid global warming

I am not kidding. Can you imagine the impact that a couple of thousand of these power plants could have. Not only that but the highest tidal differences are in the places where the impact of global warming will be the greatest.

Poetry in Motion: Power Plant Will Use Ocean Tides to Power 155K Homes

by Terry Turner –

This planned power plant in Wales may look like the Guggenheim Museum but its benefits far outweigh the beauty: it will use the rise and fall of ocean tides to generate enough renewable electricity to power 155,000 homes for 120 years.

When completed, the structure will produce electricity enough to displace more than a quarter million barrels of oil each year— while leaving virtually no carbon footprint.

Power plants have been generating electricity using the tides since 1966, but the Swansea project is the first to employ a radically new method of harnessing the natural forces. The secret lies in its nearly six-mile-long barrier wall that will enclose a huge amount of water in an artificial “tidal lagoon”.

The lagoon captures and holds seawater at high tide. As the tide goes out, water in the 4.5 square mile lagoon will be as much as 27 feet higher than the water outside its walls. This tremendous pressure will be routed through 26 turbines, rushing out to sea until the water level equalizes on both sides of the lagoon. At high tide, the flow is reversed, keeping the sea out of the lagoon until it reaches maximum height, then letting the water rush through the turbines again until it fills up the lagoon.
