Renewable Energy Makes Things Tough On The Grid, But New Software Could Help

By Bruce Watson – In 2016, more than two-thirds of power in Europe came from nonrenewable sources. Globally, renewables are expected to reach parity with coal and gas around 2040.

Nevertheless, the speed with which intermittent renewables — the sun doesn’t always shine and the wind doesn’t always blow — are coming on board is making it harder for European utilities to balance the grid. That’s because the grid, as large as it is, is also a delicate system where supply must match demand at all times or there’s a risk of blackouts.

In France, for example, strong winds in the north mixed with a sunny week on the Riviera in the south can lead to a surfeit of electricity that puts the balance at risk.

The intermittency also makes profits hard to find, with European utilities on average struggling to increase profits 1 percent in 2016. Countries around the world are watching how Europe uses thermal generation to keep the grid balanced; prioritizes low-cost, clean and renewable energy; and keeps utilities profitable amid a rapidly changing energy network. more> https://goo.gl/iC532f

The Time To Invent The Technologies That Will Power Our Future Is Now
By David Danielson – The year 2050 sounds pretty far away, doesn’t it? But in terms of the world our children and grandchildren will inherit, 2050 is today: it’s right around the corner.

By 2050, there will be almost 10 billion people on Earth, one-third more than there are today, with essentially all of this population growth predicted to be in currently less-wealthy nations around the world. And the approximately 9 billion people living in these nations in 2050 will be hungry to consume more energy, requiring an almost doubling of energy usage per person to achieve a good standard of living by some estimates.

At the same time, the world’s best scientists have determined that we must simultaneously reduce our global greenhouse gas emissions by 80 percent or more by 2050, relative to today’s levels, in order to avoid the most devastating impacts of climate change.

Scaling and improving today’s clean energy technologies can take us part of the way to the future we all want. Technologies like wind power, solar power, LEDs, electric vehicle batteries, and many others are already rapidly approaching widespread cost-competitiveness with traditional forms of energy.

But these technologies alone will not be enough: it has become clear now that to provide universal energy access around the world while simultaneously achieving required emissions reductions, we must unleash an unprecedented Energy Innovation Revolution today – and over the next few years – to develop the transformative new energy technologies that will be needed to close the gap between the 2050 we are headed for and the 2050 we want. more> https://goo.gl/57jCZr

Solar energy to Otaniemi – campus planning invests in energy efficiency
By Satu Kankaala – Right now, the Aalto University main campus is growing and developing rapidly. Campus planning is investing in energy efficiency, which is an important step in the goal towards an energy self-sufficient Otaniemi ‘According to our report, ground heat and solar energy are the most suitable options for Otaniemi, and we are gradually increasing their use’, tells Satu Kankaala, Head of Workplaces and Sustainability at Aalto CRE.

‘The campus is made unique by several culturally significant locations as well as the nearby nature and conservation area. They also impact what kinds of energy technologies can be used in the properties’, she continues.

According to Kankaala, also financial sustainability, the wellbeing of people working in the spaces, and improving the utilization of the spaces are central aspects of responsible campus development.

About 45% of the energy used for heating and 75% of the energy used for cooling the recently repaired Dipoli comes from geothermal energy. Geothermal energy will comprise about 90% of the heating and up to 95% of the cooling of Väre, which will be finished next year. The electricity consumption of campus buildings has considerably been reduced by measures such as shifting to LED lighting and improving the power management of the computer base. With these energy efficiency measures, the carbon footprint of the buildings has been significantly reduced. more> https://goo.gl/crp3uu

Our obsession with GDP and economic growth has failed us, let’s end it

BOOK REVIEW

Wellbeing Economy: Success in a World Without Growth, Author: Lorenzo Fioramonti.

By Lorenzo Fioramonti – The idea that the economic “pie” can grow indefinitely is alluring. The “growth first” rule has dominated the world since the early 20th century. No other ideology has ever been so powerful: the obsession with growth even cut through both capitalist and socialist societies.

But what exactly is growth? Strangely enough, the notion has never been reasonably developed.

For common sense people, there is growth when—all things being equal—our overall wealth increases.

Paradoxically, our model of economic growth does exactly the opposite of what common sense suggests.

Here are some examples. If I sell my kidney for some cash, then the economy grows. But if I educate my kids, prepare and cook food for my community, improve the health conditions of my people, growth doesn’t happen.

If a country cuts and sells all its trees, it gets a boost in GDP. But nothing happens if it nurtures them. more> https://goo.gl/k6G27r

Decades of Data on World’s Oceans Reveal a Troubling Oxygen Decline
By Takamitsu Ito, Shoshiro Minobe, Matthew C. Long and Curtis Deutsch – A new analysis of decades of data on oceans across the globe has revealed that the amount of dissolved oxygen contained in the water – an important measure of ocean health – has been declining for more than 20 years.

The majority of the oxygen in the ocean is absorbed from the atmosphere at the surface or created by photosynthesizing phytoplankton. Ocean currents then mix that more highly oxygenated water with subsurface water. But rising ocean water temperatures near the surface have made it more buoyant and harder for the warmer surface waters to mix downward with the cooler subsurface waters. Melting polar ice has added more freshwater to the ocean surface – another factor that hampers the natural mixing and leads to increased ocean more> stratification.

Falling oxygen levels in water have the potential to impact the habitat of marine organisms worldwide and in recent years led to more frequent “hypoxic events” that killed or displaced populations of fish, crabs and many other organisms. more> https://goo.gl/3F17TB

A world-class long jump to a more social Europe

By Patricia Scherer – Who would not like to go to a free public school in Finland or buy their groceries at a local cooperative in Italy?

Who would not want to receive quality community-based support for their grandparent suffering from dementia in some remote rural village, following the Swedish model?

Which working parent would not want to have access to all-day childcare, as in France?

And breathe in fresh air in a buzzling downtown, is the case in car-free Ljubljana, the Slovenian capital?

Who would refuse the support, rather than stigmatization, that the Danish flexicurity system provides to laid-off workers?

Would you not want to vote electronically from home, as in Estonia?

Or take part in the Irish citizens’ assembly to decide on legal and policy issues facing the society you live in today?

All that is Europe; all those are benchmarks to aspire to. more> https://goo.gl/qXmAUX

The Spiritual, Reductionist Consciousness of Christof Koch

By Steve Paulson – Consciousness is a buzzing business in neuroscience labs and brain institutes. But it wasn’t always this way. Just a few decades ago, consciousness barely registered as a credible subject for science.

Why were humans able to create civilizations that have transformed the planet?

We don’t have a precise answer. We have big brains and are, by some measure, the most intelligent species, at least in the short term. We’ll see whether we’ll actually survive in the long term, given our propensity for mass violence. And we’ve manipulated the planet to such an extent that we are now talking about entering a new geological age, the Anthropocene.

But it’s unclear why whales or dolphins—some of which have bigger brains and more neurons in their cortex than we do—why they are not called smarter or more successful. Maybe because they have flippers and live in the ocean, which is a relatively static environment. With flippers, you’re unable to build sophisticated tools.

Of course, human civilization is all about tools, whether it’s a little stone, an arrow, a bomb, or a computer. more> https://goo.gl/bmNgK6

New Projects Create a Foundation for Next-Gen Flexible Electronics
By Josh Brown – Four projects set to move forward at the Georgia Institute of Technology aim to lay the groundwork for manufacturing next-generation flexible electronics, which have the potential to make an impact on industries ranging from health care to defense.

Researchers at Georgia Tech are partnering with Boeing, Hewlett Packard Enterprises, General Electric, and DuPont as well other research institutions such as Binghamton University and Stanford University on the projects.

Flexible electronics are circuits and systems that can be bent, folded, stretched or conformed without losing their functionality. The systems are often created using machines that can print components such as logic, memory, sensors, batteries, antennas, and various passives using conductive ink on flexible surfaces. Combined with low-cost manufacturing processes, flexible hybrid electronics unlock new product possibilities for a wide range of electronics used in the health care, consumer products, automotive, aerospace, energy and defense sectors.

“Flexible electronics will make possible new products that will help us address problems associated with food supply, clean water, clean energy, health, infrastructure, and safety and security,” said Suresh Sitaraman, a professor in the George W. Woodruff School of Mechanical Engineering, who is leading Georgia Tech’s flexible electronics activities. more> https://goo.gl/qjx3UT

How Does Solar Photovoltaic Energy Work?

Evergreen Solar – The solar photovoltaic cells in your solar panels are the mechanisms which convert sunlight into energy. When you install solar panels on your house, the PV cells convert sunlight into direct current (DC) and an inverter connected to the system is what converts direct current into alternating current (AC) – which is the type of current needed to power your household appliances. This power runs through your electrical panel box, just like electricity you get from the grid, and you can potentially run your entire house on solar power than power taken from the grid.

Most residential solar energy systems are still connected to the grid. This is to allow for uninterrupted electricity in occasions when you don’t have enough solar energy to continue to power your house (e.g., on cloudy days or during the night).

If you generate enough energy from your solar panels such that you have “extra” energy left over, it will get fed back to the grid and you will get credit for this contribution of energy. Termed “net metering,” this transfer of electricity allows some customers to still maintain a $0 electric bill even when using the utility company’s energy from the grid. more> evergreensolar.com

The Electric Car Rush Started Too Early

By Leonid Bershidsky – The hyped-up electric vehicle revolution, driven by a fear of being left behind and overzealous regulation, may be forcing car companies to make expensive mistakes. The modern electric vehicle is conceptually inconsistent with how people want to use cars, and in many countries the environmental effect of switching to EVs is negligible.

To spend heavily on electrification, companies have to believe forecasts from experts who don’t have skin in the game. McKinsey, for example, recently put out a report arguing that consumer interest in electric cars is growing. All automakers need to do is keep up incremental improvements and advertising more to increase awareness.

That could turn out to be wishful thinking, because the modern EV caters to a specific-use scenario that increasingly doesn’t work for today’s consumers. more> https://goo.gl/kg48lX
