Green power takes on fossil fuels

Renewable energies are becoming globally more competitive. And an increasing number of studies are showing they have an economical edge, especially if environmental and health costs are taken into account.

Deutsche Welle, 30 Jan 2015

In Germany there is much discussion around renewable energies and cost. Fans of conventional energy sources hope to slow the rapid expansion of wind and solar power since, they say, the cost of renewable energies is too high.

The forum Green Budget Germany (FÖS) has now put forward a comprehensive study that compared all power technologies in Germany, including all known costs. Germany's energy cooperative Greenpeace Energy had commissioned the study.

Things considered were overall expenses, as well as "other effects from using conventional energies including costly consequences - for example, environmental and climate damage," said study leader Swantje Küchler from FÖS.

In the case of nuclear power, the damages after a possible nuclear accident were also taken into account. So far, the risks for large accidents worldwide have been carried by the general public, as power plant operators usually don't have the appropriate liability insurance.

Most bang for your buck

In the overall assessment, wind and solar power gave the most bang for your buck, according to calculations by FÖS. In 2014 electricity from wind and large solar power plants cost Germany between five and 10 euro cents per kilowatt-hour (kWh). In contrast, the cost of electricity from natural gas, coal or lignite power plants was distinctly higher - between 11 to 17 cents per kWh.

Particularly expensive in comparison was nuclear power. Even though no new nuclear power plants will be built in Germany, with the last reactors expected to shut down in 2022, scientists contemplated the cost of nuclear energy from fictitious new power plants. That, plus the potential harms to the environment and human health arising from accidents, raised the total cost of nuclear power to between 19 to 50 cents per kWh.

A need for transparency

Energy scientists from other institutions felt vindicated by the study.

"The results are basically consistent with our studies, which show that conventional energies are significantly more expensive than renewables," said Claudia Kemfert of the German Institute for Economic Research (DIW).

Consequently, experts are calling for honesty and transparency in the debate, in which all costs should be taken into account.

"The problem is the high costs of coal and nuclear power are hidden from customers, who pay for them indirectly. We wanted to fix this grievance," said Marcel Keiffenheim of Greenpeace Energy.

Also, the study provided good evidence to "promote the development of renewable energies as soon as possible for economic reasons."

Tackling global climate change with renewables

The International Renewable Energy Agency (IRENA) in Abu Dhabi arrived at similar results in its most recent study Renewable Power Generation Costs in 2014. They found the generation of electricity from fossil fuels took a toll on human health and climate and added up to 11 cents per kWh.

IRENA is headquartered in
oil-rich Abu Dhabi.

Since the cost of renewables in recent years has plunged worldwide, there is now "a historic opportunity to build a clean and sustainable energy supply and, therefore, prevent catastrophic climate change in an affordable way," according to Adnan Z. Amin, Director-General of IRENA.

At the same time, the march to renewables created "new jobs and reduced the import bills for fuels."

Above all, wind energy in many places in the world is economically competitive, often being cheaper than fossil fuels. According to an IRENA study, some windy places can already produce a kWh of power for four cents.

But the average production cost for wind power varies across regions. In China and Asia, it would cost around five or six; in North America, around six; and in Africa, around seven cents per kWh.

IRENA also saw much potential in the falling prices of solar power - particularly cheap in sunny countries. In the Middle East, operators of solar parks, or photovoltaic power stations, said they already generated electricity for five cents per kWh.

Renewables should also be helpful for the approximately 1.3 billion people who have up to now lived without electricity. According to IRENA's report, renewables in this case were the cheapest energy source, especially in comparison to diesel.

With a new online platform, the international agency hopes to strengthen the push for renewable energies, for which worldwide data are now available.

“…  4 - Energy (again)

The natural resources of the planet are finite and will not support the continuation of what you've been doing. We've been saying this for a decade. Watch for increased science and increased funding for alternate ways of creating electricity (finally). Watch for the very companies who have the most to lose being the ones who fund it. It is the beginning of a full realization that a change of thinking is at hand. You can take things from Gaia that are energy, instead of physical resources. We speak yet again about geothermal, about tidal, about wind. Again, we plead with you not to over-engineer this. For one of the things that Human Beings do in a technological age is to over-engineer simple things. Look at nuclear - the most over-engineered and expensive steam engine in existence!

Your current ideas of capturing energy from tidal and wave motion don't have to be technical marvels. Think paddle wheel on a pier with waves, which will create energy in both directions [waves coming and going] tied to a generator that can power dozens of neighborhoods, not full cities. Think simple and decentralize the idea of utilities. The same goes for wind and geothermal. Think of utilities for groups of homes in a cluster. You won't have a grid failure if there is no grid. This is the way of the future, and you'll be more inclined to have it sooner than later if you do this, and it won't cost as much.

Water

We've told you that one of the greatest natural resources of the planet, which is going to shift and change and be mysterious to you, is fresh water. It's going to be the next gold, dear ones. So, we have also given you some hints and examples and again we plead: Even before the potentials of running out of it, learn how to desalinate water in real time without heat. It's there, it's doable, and some already have it in the lab. This will create inexpensive fresh water for the planet. 

There is a change of attitude that is starting to occur. Slowly you're starting to see it and the only thing getting in the way of it are those companies with the big money who currently have the old system. That's starting to change as well. For the big money always wants to invest in what it knows is coming next, but it wants to create what is coming next within the framework of what it has "on the shelf." What is on the shelf is oil, coal, dams, and non-renewable resource usage. It hasn't changed much in the last 100 years, has it? Now you will see a change of free choice. You're going to see decisions made in the boardrooms that would have curled the toes of those two generations ago. Now "the worst thing they could do" might become "the best thing they could do." That, dear ones, is a change of free choice concept. When the thinkers of tomorrow see options that were never options before, that is a shift. That was number four. ….”

Home cheap home: Vietnam architect's quest for low-cost housing

Yahoo – AFP, Cat Barton, 25 Jan 2015

Long An (Vietnam) (AFP) - Vo Van Duong's bamboo and coconut leaf house looks much like others deep in Vietnam's Mekong Delta. But unlike them, his seemingly simple abode is designed to withstand typhoons, flooding and earthquakes -- and at a cost of less than $4,000 could herald a new wave of cheap, sustainable housing.

The natural materials on its surface belie the hi-tech internal structure of the farmer's new home, which uses steel struts and wall panels as a defence against the elements in this natural disaster-prone region.

"The new house is safer, I'm not afraid that it will collapse," the 48-year-old papaya farmer told AFP inside the house he moved into nine months ago.

Duong is testing a prototype by an award-winning Vietnamese architecture firm looking for low-cost housing solutions for communities vulnerable to climate change.

His S-House 2 was free, but if rolled-out on a wider scale could be sold for less than $4,000.

"There was water coming down from the roof in my old house. Sometimes, when there was a strong wind, I was so afraid the house wouldn't survive," Duong said, adding his new home was the envy of his neighbours.

The eco-home is the brainchild of Vo Trong Nghia, who joins other architects around the world in trying to fill a demand for cheap and easy to assemble housing -- from flat-pack refugee shelters to shipping-container homes for tsunami victims.

He says all architects have a duty to help the poor.

"What about those with low income, billions of them, how can they live?" Nghia told AFP. "They have the right to live in comfortable, functional places."

But he wants to go further, creating a home residents can take pride in.

"I don't want people to be looking at it as 'cheap houses' but as resort-quality accommodation close to nature, so (residents) can live a life of the highest quality."

Flat-pack homes

The design is still being refined by his team, who are eventually aiming to create a flat-pack home. The newest version, S-House 3, can be built by five people in three hours.

"Our goal for S-house is for the owner to construct it by themselves," said Kosuke Nishijima, a partner at the firm.

The latest design also allows for multiple houses to be tacked together, a function that could allow, for example, the construction of a storm-proof school easily transportable to remote areas or a larger family home.

Nghia has already been approached by NGOs in disaster-prone Bangladesh and the Philippines, but is not yet ready to supply the house commercially.

From saline-intrusion and flooding in the Mekong Delta to typhoons along the central coast, Vietnam is also home to communities living in high risk areas.

For decades, Vietnamese families have adapted their houses themselves, many building ad hoc mezzanines to avoid flooding.

In more recent years organisations including the Red Cross and Women's Unions, as well as local authorities, have been trying to help people develop more resilient housing.

But in order to ensure such projects are successful, "private architects' support is critical", according to Boram Kim, an urban specialist with UN-Habitat in Vietnam.

"State and local government authorities are well aware that such houses are needed for the poor, but have little technical knowledge for realising their ideas," she told AFP.

"Architects have technical knowledge for reducing the housing construction cost while making it storm proof," she said, cautioning that it was important for designers to listen to the needs of local communities.

Architect for the poor

Nghia's firm found that one of the problems facing rural Vietnamese living in traditional bamboo shacks or stilted river-bank dwellings is the costly upkeep they require to withstand increasingly extreme weather.

Although the S-House 2's outer casing of coconut leaf may need replacing every four years, the structure itself should require no expensive maintenance, said engineer Lien Phuoc Huy Phuong.

"It can last a long time, the structure is sound," he told AFP during a tour of the small building. 

Despite its solid exterior, the house is spacious and airy inside, with large windows and doors to bring residents closer to nature.

"We tried to design this house with the best ventilation system, with spaces by the roof and windows for better air flow," Phuong said, pointing out strategic gaps that should reduce the need for electric fans.

Architect Nghia, who used bamboo as a key element in Vietnam's country pavilion for the 2010 World Expo in Shanghai, has long sought to incorporate natural and local materials into his work.

One of his first projects in Vietnam's Ho Chi Minh City was an ecologically-conscious take on a traditional Vietnamese tube home, known as Stacking Green house.

Built in 2011 for around $150,000, the building is made of a series of concrete slabs and gaps filled with plants to provide privacy while still allowing plenty of air and light.

Nghia is in strong demand for high-end projects from hotels to private houses, but said the low-cost S-House is his personal obsession.

"I want to live in S-House. If my family will agree," he said.

Bill Gates drinks cup of water that used to be human poop (VIDEO)

RT.com, January 07, 2015

Billionaire activist Bill Gates is backing an innovation in water filtration that turns human poop into drinking water. The OmniProcessor could bring clean water to millions of people and help solve the problem of debilitating diseases.

The OmniProcessor, designed and built by Seattle engineering firm Janicki Bioenergy, burns human waste to produce electricity and water. The processor powers itself through the use of a steam engine and does not emit an odor. The machine could handle 14 tons of waste from 100,000 people, producing up to 86,000 liters of drinkable water a day, and net 250 kw of electricity.

At a demonstration of the OmniProcessor shown on GatesNotes, a smiling Bill Gates drank water from the machine, which was previously untreated sewage.

“It’s water,” said Gates in the video.

He wrote on his blog: "The water tasted as good as any I’ve had out of a bottle. And having studied the engineering behind it, I would happily drink it every day. It’s that safe."

Gates said that 2.5 billion people – or 40 percent of the global population – have no access to safe sanitation, and many people use facilities that do not safely dispose of human waste. About 1.5 million children die every year from contaminated food and water, and half of all patients in hospitals are there because of problems with water and sanitation. It is extremely costly to try and create sewage infrastructure in cities and towns that already exist, so Gates thinks the low cost water treatment machine could be revolutionary.

“If you can get thousands of these things out there, then you’ve ensured the people really will grow up in a healthy way,” Gates told Wired. “They’ll live much higher quality lives. You will save a lot of lives. And you’ll have local entrepreneurs who are maintaining these things.”

The OmniProcessor, which costs $1.5 million, will undergo a pilot launch in Dakar, Senegal later this year.

"2013 - What Now ?" – Jan 6, 2013 (Kryon Channelling by Lee Caroll) - (Text version)

“… New ideas are things you never thought of. These ideas will be given to you so you will have answers to the most profound questions that your societies have had since you were born. Inventions will bring clean water to every Human on the planet, cheaply and everywhere. Inventions will give you power, cheaply and everywhere. These ideas will wipe out all of the reasons you now have for pollution, and when you look back on it, you'll go, "This solution was always there. Why didn't we think of that? Why didn't we do this sooner?" Because it wasn't time and you were not ready. You hadn't planted the seeds and you were still battling the old energy, deciding whether you were going to terminate yourselves before 2012. Now you didn't…. and now you didn't.

It's funny, what you ponder about, and what your sociologists consider the "great current problems of mankind", for your new ideas will simply eliminate the very concepts of the questions just as they did in the past. Do you remember? Two hundred years ago, the predictions of sociologists said that you would run out of food, since there wasn't enough land to sustain a greater population. Then you discovered crop rotation and fertilizer. Suddenly, each plot of land could produce many times what it could before. Do you remember the predictions that you would run out of wood to heat your homes? Probably not. That was before electricity. It goes on and on.

So today's puzzles are just as quaint, as you will see. (1)How do you strengthen the power grids of your great nations so that they are not vulnerable to failure or don't require massive infrastructure improvement expenditures? Because cold is coming, and you are going to need more power. (2) What can you do about pollution? (3) What about world overpopulation? Some experts will tell you that a pandemic will be the answer; nature [Gaia] will kill off about one-third of the earth's population. The best minds of the century ponder these puzzles and tell you that you are headed for real problems. You have heard these things all your life.

Let me ask you this. (1) What if you could eliminate the power grid altogether? You can and will. (2) What if pollution-creating sources simply go away, due to new ideas and invention, and the environment starts to self-correct? (3) Overpopulation? You assume that humanity will continue to have children at an exponential rate since they are stupid and can't help themselves. This, dear ones, is a consciousness and education issue, and that is going to change. Imagine a zero growth attribute of many countries - something that will be common. Did you notice that some of your children today are actually starting to ponder if they should have any children at all? What a concept! ….”
