“Today, China invests more each year in wind, hydro and solar power than any other country on earth. This week it further underlined its role as the global leader in renewable energy by switching on the world’s largest floating solar power plant.
The facility is located in the city of Huainan, in China’s eastern Anhui province. It has a capacity of 40 megawatts (MW), enough to power a small town. And in a stroke of pleasing symbolism, the plant floats over a flooded former coal-mining region. “
https://www.weforum.org/agenda/2017/06/china-worlds-largest-floating-solar-power/
 
“More than 2.5 million people work in the solar power sector alone in China, compared with 260,000 people in the U.S., according to the most recent annual report from the International Renewable Energy Agency. …
Coal still makes up the largest part of China's energy consumption, but Beijing has been shutting coal mines and set out plans last year to cut roughly 1.3 million jobs in the industry. The Chinese government has also moved to restrict the construction of new coal power plants.
For the first time ever, China's National Energy Administration in January [date?] established a mandatory target to reduce coal energy consumption. It also set a goal for clean energy to meet 20% of China's energy needs by 2030.
Analysts expect China to easily meet that target. Greenpeace noted in a report earlier this year that the country's clean energy consumption rose to 12% at the end of 2015. Renewable energy sources account for about 10% of total U.S. energy consumption, according to official statistics. “
http://money.cnn.com/2017/07/18/technology/china-us-clean-energy-solar-farm/index.html
 
“By 2030, China aims to generate a fifth of its energy from renewable sources. Coal consumption has been falling for the last three years in a row. This may not be good news for coal producers—China gobbles 50 percent of the world's total output—it is certainly good news for pretty much everyone else….China is betting on solar, and it's betting big. It may well turn from the biggest polluter into the most vocal advocate of climate action. It's only in its best interest - all those coal miners losing their jobs with the shutdown of mine and the shift to cleaner energy will need jobs, for one. For another, it is important for the world's second-largest energy consumer to reduce its dependence on imported energy. All very good reasons to go renewable and do it quickly.”
http://www.businessinsider.com/china-completed-the-worlds-biggest-floating-solar-energy-farm-2017-6
 
“And not just for coalminers. China has some of the world’s worst air pollution, which scientists say may contribute to a third of deaths, and regularly grounds flights and keeps children entombed in their homes and classrooms. Coal burnt for power and steel smelting is the principle cause, as soot-stained miners burrow China into what’s the world’s second largest economy today. But the nation, like Sang, is changing tack and embracing sustainability—no longer beholden to the singular tenet of growth at any cost.

China is now the world’s largest renewable energy investor. The government promises to spend $360 billion on clean energy projects by 2020, creating 13 million new jobs in the process. And as the Huainan project demonstrates, the Asian superpower is pushing the boundaries of green tech, whether wind, solar or hydropower.

New panels are being developed specifically for arid deserts and others to withstand sultry rainforests. “China is leading the way in terms of finding green solutions,” says Wu Changhua, Greater China director for the Climate Group.”

“The renewables rollout has not been without its troubles. Vast fields of wind turbines have been erected in the country’s sparsely populated northwest, far from the big cities where electricity is most needed, and the construction of transmission lines to move all that power has failed to keep up.

‘They set up these huge wind farms and they don’t have connections to the grid,’ says Antung Liu of Indiana University Bloomington. ‘They just have this attitude that ‘We’ll build it, and hopefully we’ll be able to use it later.’
What’s more, grid operators have shown a bias toward coal production, so renewable power has sometimes gone unused even when the physical connections are there. Greenpeace estimates that 19 percent of Chinese wind power was wasted in the first three quarters of last year.

Leaders are now starting to reckon with those issues, installing new power lines and focusing on building smaller wind and solar farms in populated areas.

Not far from Jinko’s factory, another arm of the company operates just such an array. Inside rows of long, low buildings, a new season’s crop of mushrooms are about to be planted. They don’t need sunlight, so the greenhouse roofs have been given over to solar panels. Nearly 19,000 of them, mounted in rows overhead, generate electricity that is fed into the grid.
At first, China’s effort ‘was only about getting the gigawatts up,’ says Jukka-Pekka Mäkinen, CEO of The Switch, a Finland-based company manufacturing wind-power components in China. ‘Now it’s keeping up the gigawatts, but doing it much smarter, and focusing in areas where the consumption is.’

Despite such efforts, China is also still building coal-fired power plants, in part because of an incentive structure that encourages provincial officials to green-light unnecessary construction, even as the central government seeks to push cleaner options. But officials have also begun cancelling some that are already in the planning pipeline, aware that China already has more coal-fired power generation than it needs.”
http://news.nationalgeographic.com/2017/05/china-renewables-energy-climate-change-pollution-environment/
 
“It’s worth taking a minute to appreciate the sheer scale of what China is doing in solar right now. In 2015, the country added more than 15 gigawatts of new solar capacity, surpassing Germany as the world’s largest solar power market. China now has 43.2 gigawatts of solar capacity, compared with38.4 gigawatts in Germany and 27.8 in the United States.

According to new projections, it seems that trend is going to continue. Under its 13th Five Year Plan, China will nearly triple solar capacity by 2020, adding 15 to 20 gigawatts of solar capacity each year for the next five years, according to Nur Bekri, director of the National Energy Administration. That will bring the country’s installed solar power to more than 140 gigawatts. To put that in context, world solar capacity topped 200 gigawatts last year and is expected to reach 321 gigawatts by the end of 2016.

Of course, China is also the world’s largest carbon emitter, it burns more coal than any other nation, and its solar capacity is only a small fraction of its total energy portfolio. What’s more, capacity does not always equate to generation: the National Energy Administration estimates that nearly one-third of solar capacity in Gansu province, and more than one-quarter in Xinjiang, was idle last year.”
https://www.technologyreview.com/s/601093/china-is-on-an-epic-solar-power-binge/
 
“The transformation is nothing without the corresponding decrease in fossil fuels, and China seems to be making strong headway towards its goals to decrease its coal usage and import. 2015 saw coal consumption decline 3.7%, year-over-year, and net coal imports dropped a much more significant 30.4% year-over-year, down to 198.7 million tonnes. This trend has already been seen to continue into 2016, with January’s net coal imports dropping by 11.6% year-over-year.
“IEEFA [Energy Finance Studies at the Institute for Energy Economics and Financial Analysis]  forecasts that China will install an additional 22 GW of wind, 16GW of new hydro, another 6GW of nuclear, and 18GW of solar (60% utility scale, 40% distributed rooftop solar) in 2016,’ explained Buckley.’“With electricity demand forecast to grow by 3.0-3.5% yoy in 2016, this 62GW of additional zero carbon electricity capacity will be more than sufficient to meet total electricity demand growth, such that coal consumption is forecast to fall again in 2016.””
https://cleantechnica.com/2016/03/06/china-renewable-growth-soars-fossil-fuel-use-declines/
 
“China currently hosts the world’s largest number of solar power plants with a total capacity of close to 80GW last year, according to the International Energy Agency. The installation in China is nearly twice the amount of the US.
Nearly half of the nation’s total capacity was added last year. Industrial experts have also predicted that new solar farms completed this year will exceed 2016’s record, according to Bloomberg.

This neck-breaking pace was driven by government’s drive to diversify the country’s energy supply structure, which at present relies heavily on fossil fuels such as coal and imported oil.

But the solar plants are relatively short-lived, and the government does not have any retirement plan for them yet.
A panel’s lifespan ranges from 20 to 30 years, depending on the environment in which they are used, according to the US Department of Energy. High temperatures can accelerate the ageing process for solar cells, while other negative factors – such as the weight of snow or dust storms – could cause material fatigue on the surface and internal electric circuits, gradually reducing the panel’s power output.”
https://www.scmp.com/news/china/society/article/2104162/chinas-ageing-solar-panels-are-going-be-big-environmental-problem
 
“This week, media welcomed the completion of what may well be the world's largest floating solar farm, in the eastern Anhui province. The 40 MW installation sits on a flooded coal-mining town, which adds a kind of poetic element to the story - a shift away from coal and to solar and wind. But poetry is certainly not the reason why this location was selected: according to a local government source, the cool surface of the water will improve power generation.

The floating farm is the latest demonstration that China is serious about its green energy plans. Earlier this year, Beijing said it would splash US$361 billion on expanding the country's renewable power capacity by 2020. By 2022, China should have 320 GW of wind and solar power capacity, along with 340 GW of hydropower.

These plans earned it the top spot in E&Y's raking of the top 40 renewable energy markets, followed by India, who has plans for 175 GW of renewable energy by 2022. That China is in the top spot is no wonder, given that China was the biggest spender on renewable energy globally in 2015, allocating US$102.9 billion, or 36 percent of the total spent on renewables in the world that year, according to the UN Environment Programme. Last year, China installed 35 GW of solar power generation capacity, which, according to one Greenpeace expert quoted by the National Geographic, equals the total solar capacity of Germany.

By 2030, China aims to generate a fifth of its energy from renewable sources. Coal consumption has been falling for the last three years in a row. This may not be good news for coal producers—China gobbles 50 percent of the world's total output—it is certainly good news for pretty much everyone else. “

“A 2,000 foot-long floating pipe nicknamed Wilson is about to start its mission to collect all the “plastic in the middle of the Pacific Ocean.

Last month, the Ocean Cleanup foundation launched the world's first ocean cleanup system out of San Francisco to take on the notorious "Great Pacific Garbage Patch," a giant floating trash pile between San Francisco and Hawaii that is twice the size of Texas. It's the largest of five ocean trash piles on Earth.”
 
A 3:29 minutes video starts the article.
https://www.cnn.com/2018/10/15/tech/ocean-cleanup-project/index.html
 
“The Great Pacific Garbage Patch is now twice the size of Texas and contains 1.8 trillion pieces of trash floating in the ocean. The Ocean Cleanup is an ambitious non-profit committed to removing it, and on Saturday it launches its first system out to sea from the San Francisco Bay.

Dutch entrepreneur Boyan Slat came up with the idea when he was 16 years old.

‘I went scuba diving in Greece and I actually saw more plastic bags than fish around me,’ said the Ocean Cleanup CEO and founder. ‘I wondered, why can't we just clean this up?’
He founded the organization in 2013 and the team has raised $35 million through crowdfunding campaigns and big donors like Marc Benioff and Peter Thiel.

System 001 is a 600 meter long float, with a 3 meter skirt and it's designed to corral plastic and debris. The collected garbage will then be removed by garbage truck-like ships.

The initial contraption will be used for testing and aims remove about 50 tons of the garbage, but the goal is to launch 60 systems to reduce the floating garbage patch by 50 percent in the next five years.”
https://www.cnbc.com/2018/09/07/ocean-cleanup-launches-to-take-on-the-great-pacific-garbage-patch.html
 
“Ocean currents concentrate plastic in five areas in the world: the subtropical gyres, also known as the world’s "ocean garbage patches". Once in these patches, the plastic will not go away by itself. The challenge of cleaning up the gyres is the plastic pollution spreads across millions of square kilometers and travels in all directions. Covering this area using vessels and nets would take thousands of years and cost billions of dollars to complete. How can we use these ocean currents to our advantage?”
https://www.theoceancleanup.com/
 
“In 2013, the Ocean Cleanup Foundation was established by an 18-year-old dutch inventor named Boyan Slat. According to the foundation’s site, it was begun with the goals of creating ways to clear the Pacific Ocean of Pollution and educating people on the Great Pacific Garbage Patch.

The idea, Slat hypothesized, was to use the ocean’s currents to our advantage, allowing our passive drifting systems to clean up over half of the Great Pacific Garbage Patch in about 5 years’ time. Slat proposed that it would be nearly impossible to go after the garbage in the ocean with nets and vessels, and more than that, it would be costly and time-consuming.

With this in mind, he devised an Ocean Cleanup Passive System that would be comprised of a floater with a solid screen underneath that would concentrate debris and lead them to a collection system. Then, that system would be slowed to the point that it moved less quickly than the plastic, which would result in the plastic being trapped.

The technology behind the Ocean Cleanup Project is fairly simple, but compelling. With their solid screens underneath floating pipes, debris can be caught both on and under the surface. These systems will be drifting freely about the Pacific Ocean and will help to concentrate plastic towards a central point for collection by vessels, where it can be easily removed.”
https://businessconnectworld.com/2018/02/21/the-ocean-cleanup-project/
 
“The Ocean Cleanup plans to monitor the performance of the beta, called System 001, and have an improved fleet of 60 more units skimming the ocean for plastics in about a year a half. The ultimate goal of the project, founded by Dutch inventor Boyan Slat when he was 18, is to clean up 50% of the patch in five years, with a 90% reduction by 2040.”
https://www.forbes.com/sites/jeffkart/2018/08/28/the-ocean-cleanup-is-starting-aims-to-cut-garbage-patch-by-90-by-2040/#40e5d1bb253e
 
“Many ocean experts have expressed optimism the project may go a long way to cleaning up the massive debris field, but some lingering concerns still remain.

Developers insist marine life will not get caught by the barrier and will be able to slip under the three metre deep skirt it uses to collect plastic.”
https://www.independent.co.uk/news/science/great-pacific-garbage-patch-ocean-cleanup-system-001-launch-amount-plastic-sea-pollution-a8528836.html
“…Sue Kinsey, of the Marine Conservation Society, warned creatures that float on the water’s surface, such as jellyfish, would be unable to escape.

‘The major problem is those creatures that passively float in the ocean that can’t actually move out of the way – once they’re in this array, they’re going to be trapped there unable to move,’ she told the BBC.”
 
‘[M]any in the marine biology and oceanographic world worry that it could keep the public from focusing on the real problem – stopping the seemingly endless flow of trash into the oceans in the first place. 

While Rolf Halden, a professor of environmental health engineering at Arizona State University, applauds the effort, he says cleaning while trash pours in doesn't make much sense.

"If you allow the doors to be open during a sandstorm while you’re vacuuming," he said, "you won’t get very far.’ “

“Governments around the world must take "rapid, far-reaching and unprecedented changes in all aspects of society" to avoid disastrous levels of global warming, says a stark new report from the global scientific authority on climate change.
The report issued Monday by the UN Intergovernmental Panel on Climate Change (IPCC), says the planet will reach the crucial threshold of 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial levels by as early as 2030, precipitating the risk of extreme drought, wildfires, floods and food shortages for hundreds of millions of people.

The date, which falls well within the lifetime of many people alive today, is based on current levels of greenhouse gas emissions.

The planet is already two-thirds of the way there, with global temperatures having warmed about 1 degree C. Avoiding going even higher will require significant action in the next few years.

"This is concerning because we know there are so many more problems if we exceed 1.5 degrees C global warming, including more heatwaves and hot summers, greater sea level rise, and, for many parts of the world, worse droughts and rainfall extremes," Andrew King, a lecturer in climate science at the University of Melbourne, said in a statement. “
https://www.cnn.com/2018/10/07/world/climate-change-new-ipcc-report-wxc/index.html
 
“The authors found that if greenhouse gas emissions continue at the current rate, the atmosphere will warm up by as much as 2.7 degrees Fahrenheit (1.5 degrees Celsius) above preindustrial levels by 2040, inundating coastlines and intensifying droughts and poverty. Previous work had focused on estimating the damage if average temperatures were to rise by a larger number, 3.6 degrees Fahrenheit (2 degrees Celsius), because that was the threshold scientists previously considered for the most severe effects of climate change.
The new report, however, shows that many of those effects will come much sooner, at the 2.7-degree mark. …

To prevent 2.7 degrees of warming, the report said, greenhouse pollution must be reduced by 45 percent from 2010 levels by 2030, and 100 percent by 2050. It also found that, by 2050, use of coal as an electricity source would have to drop from nearly 40 percent today to between 1 and 7 percent. Renewable energy such as wind and solar, which make up about 20 percent of the electricity mix today, would have to increase to as much as 67 percent.”
https://www.nytimes.com/2018/10/07/climate/ipcc-climate-report-2040.html
 
“The world is currently 1C warmer than preindustrial levels. Following devastating hurricanes in the US, record droughts in Cape Town and forest fires in the Arctic, the IPCC makes clear that climate change is already happening, upgraded its risk warning from previous reports, and warned that every fraction of additional warming would worsen the impact.

Scientists who reviewed the 6,000 works referenced in the report, said the change caused by just half a degree came as a revelation. “We can see there is a difference and it’s substantial,” Roberts said.

At 1.5C the proportion of the global population exposed to water stress could be 50% lower than at 2C, it notes. Food scarcity would be less of a problem and hundreds of millions fewer people, particularly in poor countries, would be at risk of climate-related poverty.”
https://www.theguardian.com/environment/2018/oct/08/gloglo-warming-must-not-exceed-15c-warns-landmark-un-report

“The past decade has seen an astonishing run of record-breaking storms, forest fires, droughts, coral bleaching, heat waves, and floods around the world with just 1.8 degrees Fahrenheit (1.0 degrees Celsius) of global warming. [See: Hidden Costs of Climate Change Running Hundreds of Billions a Year] But much of this will get substantially worse with 2.7 degrees Fahrenheit of warming, and far worse at 3.6 degrees Fahrenheit (2 degrees Celsius), according to the IPCC’s “Special Report on Global Warming of 1.5°C”, released Sunday and examining more than 6,000 studies.”
https://www.nationalgeographic.com/environment/2018/10/ipcc-report-climate-change-impacts-forests-emissions/
 
“The IPCC’s Special Report lays out various pathways to stabilize global warming at 2.7 degrees Fahrenheit (1.5 degrees Celsius). These solutions all require unprecedented efforts to cut fossil-fuel use in half in less than 15 years and eliminate their use almost entirely in 30 years. This means no home, business, or industry heated by gas or oil; no vehicles powered by diesel or gasoline; all coal and gas power plants shuttered; the petrochemical industry converted wholesale to green chemistry; and heavy industry like steel and aluminum production either using carbon-free energy sources or employing technology to capture CO2 emissions and permanently store it.

In addition, depending on how fast emissions are cut, between 0.4 and 2.7 million square miles (1-7 million square kilometers) of land may have to be converted to growing bioenergy crops and up to 3.86 million square miles (10 million square kilometers) of forests added by 2050. And still that won’t be enough, the report warns. Every pound of CO2 emitted in the last hundred years will continue to trap heat in the atmosphere for hundreds of years to come. By 2045 or 2050 there will still be too much CO2 in the atmosphere. More forests or some form of direct capture that takes CO2 out of the atmosphere will be essential to stabilize global temperatures at 2.7 degrees Fahrenheit (1.5 degrees Celsius), the report says.”

The book Chemistry on a Budget contains chemistry labs that are useful with inexpensive, easy to obtain materials.
 
For the 2018-19 school year, buy a copy of the lab book Chemistry on a Budget.  It’s a great resource for your class!

There are two versions of each lab, one with a ten-question conclusion and one with directions for a full lab report.  This way the teacher has the option!  Each lab is two pages to allow for one two-sided handout. 
 
A 5-Star Customer Review of Chemistry on a Budget at amazon.com states:
“[S]traight forward, to the point, using household chemicals…this is the lab book for you. 
I teach high school chemistry and this is exactly what [I] was looking for. Labs included simple household chemicals that could be easily found. Nice format, easy to follow along procedures, and touches on every topic of our chemistry curriculum.”

You can buy this lab book for $23 at amazon.com or lulu.com. It will take 1-2 weeks to get to you -- Order Now.  It’s a great resource!
