Comments Off on Pollution cuts solar energy production by up to 35%

We may be sabotaging our efforts to generate clean energy . New research from a team led by Duke University found polluted air may be reducing our solar energy output – by 25 percent. And areas with some of the highest investment in solar power are those impacted the most: China , the Arabian Peninsula, and India . Dust and airborne particles may be harming our ability to generate as much solar energy as we can. Duke University engineering professor Michael Bergin said, “My colleagues in India were showing off some of their rooftop solar installations, and I was blown away by how dirty the panels were. I thought the dirt had to affect their efficiencies, but there weren’t any studies out there estimating the losses. So we put together a comprehensive model to do just that.” Related: Students Create Award-Winning Robot That Cleans Solar Panels Joined by researchers from the Indian Institute of Technology Gandhinagar (IITGN) and the University of Wisconsin at Madison , Duke University scientists found pollution accumulation is indeed impacting solar energy output. They measured the decrease in energy from IITGN’s solar panels as they got dirtier. Each time the panels were cleaned after several weeks, the researchers noted a 50 percent boost in efficiency. China, India, and the Arabian Peninsula are the areas of the world impacted the most. Even if their panels are cleaned monthly, they still could be losing 17 to 25 percent of solar energy production. And if the cleanings happen every two months, the losses are 25 or 35 percent. Reduced output costs countries not just in electricity but money as well. Bergin said China could lose tens of billions of dollars yearly, “with more than 80 percent of that coming from losses due to pollution.” He pointed out we’ve known air pollution is bad for health and climate change , but now we know it’s bad for solar energy as well – all the more reason for politicians to adopt emissions controls. The research was published online this month by the journal Environmental Science and Technology Letters . Via Duke University Images via Duke Engineering on Twitter and Pexels

Comments Off on India to only sell electric cars by 2030

India is taking huge strides to escape its dubious distinction as one of the most polluted countries on Earth. The government is taking dramatic measures to clean the country’s air – including the switch to sell solely electric cars in just 13 years. If the amount of diesel and petrol cars dwindles on the streets of India, the country could lower the dangerous levels of air pollution that have led to the deaths of 1.2 million people annually. Energy minister Piyush Goyal said India would financially back the move for the first two to three years; then electric vehicle production will be “driven by demand and not subsidy.” Related: New Delhi has the worst air pollution of any city on earth The move has been praised by environmentalists and, naturally, worried the oil industry. India is the third biggest oil importer in the world – each year they spend $150 billion on oil. Moving to electric cars could save the country $60 billion in energy expenses. Indian car owners would also save money by switching to electric vehicles . Goyal, who presented the government’s plan at the Confederation of Indian Industry Annual Session 2017 in New Delhi, said the government would invest in charging infrastructure, beginning in big urban areas like Delhi. He also said they were considering methods like swapping batteries “so cars don’t have to wait for batteries to be charged,” saying, “Electric cars can then move to petrol pumps, swap their batteries, and drive out, just like they do now. And it will take less time than what it takes to put petrol in your car, like in Formula 1 races!” The transition to electric cars would also help the country slash greenhouse gas emissions. Calculations indicate India’s carbon emissions could decrease 37 percent by 2030 with the move to electric vehicles.

Comments Off on It took more than 25 years to build this incredible walkable world map

You’d need around 11 years to walk around the globe – if you can walk on water. But a world map in Denmark makes the feat possible in a few minutes. Verdenskortet , or world map , is a walkable map , made of soil and stone, built on top of a pond. It took Søren Poulsen more than two decades to complete this extraordinary project, and it was worth the wait. Poulsen, who was born in 1888 in Denmark, realized a stone on his land was shaped similar to the Jutland Peninsula. That stone launched the idea to create a world map, and Poulsen started the project in 1944. He continued working on the map, located at his childhood home at Klejtrup Lake, until he died in 1969. Today the map comprises the center of a park offering outdoor activities and event space. Around 35,000 people visit every single year. Related: Our World: A Giant Pixelated LEGO Map Built from 1 Million Bricks! Poulson made the map out of rocks and dirt, using just hand tools, a pushcart, and a wheelbarrow. The Verdenskortet Facebook page explains the stones comprising the world map were moved onto the ice during winter, and then in spring the stones could be moved into place. Flags mark each country, and there’s even yellow bricks dividing America up into states. Red poles indicate where the equator lies. The world map is 300 feet by 150 feet, and every 10 inches represents around 69 miles in the real world. Today the park offers guided tours of Verdenskortet, paired with coffee and cake. People can play miniature golf on the grass, or take a class field trip to the map. Visitors can take a boat trip around the mini Pacific Ocean , and on land go on pony rides, play old Viking games, or jump on a trampoline. Park entry is inexpensive; around $12 for adults and $8 for kids. + Verdenskortet Via GOOD Images via Verdenskortet Facebook

BREAKING: Trump announces U.S. will withdraw from the Paris Climate Agreement

Comments Off on BREAKING: Trump announces U.S. will withdraw from the Paris Climate Agreement

During a highly anticipated speech at the Rose Garden, climate denier President Donald Trump announced that the United States of America will withdraw from the Paris Climate Agreement secured under Barack Obama’s leadership. President Trump stated that the accord was “bad” and poorly negotiated by the Obama administration, and that he “is keeping his campaign promise to put American workers first.” Part of Trump’s speech read, ”The Paris Accord is a BAD deal for Americans, and the President’s action today is keeping his campaign promise to put American workers first. The accord was negotiated poorly by the Obama administration and signed out of desperation. It frontloads costs on the American people to the detriment of our economy.” Before the announcement was officially made, Donald Trump was cited by The Daily Best telling congressional staffers on a conference call that he is withdrawing from the Paris accord. Energy policy adviser for the White House, Michael Catanzaro, confirmed that “the United States is getting out of the Paris agreement.” Catanzaro added that Trump “will be open to and will immediately be looking for a better deal.” Reportedly, the Trump administration will follow steps for withdrawal laid out in the agreement. In total, says Catanzaro, removing the U.S. from the deal will take four years. “But we’re going to make very clear to the world that we’re not going to be abiding by what the previous administration agreed to,” he said. Despite the fact that countries such as Costa Rica run on 100% renewable energy and Denmark once generated 400% of the power it needs from wind turbines , the Trump administration remains resistant to transitioning the U.S. to run on renewable energy resources. This is because President Trump, a businessman, believes that energy sourced from fossil fuels is the solution to making America great again – and he thinks climate change is a “hoax” invented by the Chinese . Related: China says they’ll stay in the Paris Agreement – with or without Trump At the time of its signing, 195 countries, including the United States, pledged to reduce emissions that contribute to climate change in order to prevent global catastrophes which may result from rising temperatures. President Barack Obama committed America to a goal of lowering emissions by 26 percent to 28 percent below 2005 levels by 2025. The broad aim was to increase these cuts over time. With the United States exiting the Paris Agreement, carbon emissions are likely to increase, potentially propelling global disasters resulting from rising sea levels , severe weather conditions, and increased temperatures. On a positive note, China and the European Union are prepared to publicly recommit to the agreement with or without the United States. Also, Trump cannot technically withdraw from the agreement until November of 2019. Finally, many U.S.-based companies, including Apple , have ambitious goals to run on 100% clean energy in the near future. With support from educated consumers, the U.S. may reach its previously contracted emissions goal with or without the President’s support. Via CNN Images via Pixabay , Wikimedia Creative Commons

Scientists invent graphene paint that makes your house super efficient

Comments Off on Scientists invent graphene paint that makes your house super efficient

Graphene – the strongest material known to science – is used to create everything from condoms to night-vision contact lenses. Now, thanks to the ingenuity of  The Graphene Company , paint containing the world’s “thinnest, strongest and most conductive” substance is hitting shelves in the UK. The new lime-based paint is incredibly thin, beneficial for the environment and capable of making your home, or any building, more efficient. Because  Graphenstone is composed of a lime-base with a hexagonal lattice of carbon atoms one atom thick thanks to the inclusion of graphene , the lime-based paint has superconductivity , which means it can improve the thermal regulation of buildings. As Dezeen reports , this means the invention lowers the necessity for heating and air conditioning. According to The Graphene Company director, Patrick Folkes, ”When used on interior wall surfaces, rather than heat being radiated through the walls, the graphene within the paint captures the heat. It then conducts the heat through the paint, and across the whole Graphenstone-painted surface of interior walls. This enhances the insulation measures used in buildings by slowing heat conduction through walls and out of buildings.” Because graphene is one atom thick in the paint, less is required to achieve a durable finish that is resistant to corrosion. One liter of paint would cover two eight-meter-square coats, says The Graphene Company. An additional benefit is that the paint is extremely eco-friendly . With a base made from 98 percent pure lime, the paint purifies the surrounding air as it absorbs carbon dioxide. For this reason, the company boasts it is “the most sustainable and eco-friendly paint in the world”. “Sustainability is becoming more and more important as people realise the damage that acrylics do to the environment throughout the manufacturing process and its use on walls,” said Folkes. “Graphene’s inclusion in paints, coatings and other building materials exponentially enhances hardness, durability, compression, tensile strength, elasticity, and coverage.” Related: New graphene super batteries charge up in seconds and last virtually forever After the paint is applied, a hard shell forms as the lime hardens up in the carbonization process. According to Folkes, the initial consistency is a “little bit watery.” Over a period of 10 days, however, hard coverage is provided. The best part? No fumes are released in the process. Already, the product has been used to coat the walls of hospitals , hotels, and schools. As demand for the graphene paint increases, it will likely be sold elsewhere in the world. + The Graphene Company Via Dezeen Images via The Graphene Company

Comments Off on Switzerland votes to ban nuclear power and invest in renewable energy

Switzerland just passed a new energy law that promotes renewable energy and bans nuclear power plants. The landmark vote brings the nation closer to meeting its goal of generating 4,400 gigawatt-hours (GWh) of renewable energy by 2020, and 11,400 GWh by 2035. Over the weekend, approximately 42% of the population turned up to vote in the national referendum, which marks the eighth time in recent history Swiss citizens have voted on the issue. Though the Energy Strategy 2050 was approved by Parliament last year, the country’s right wing Swiss People’s Party challenged the reform to the referendum in an attempt prevent the move from taking place. The move to initiate the reform passed easily with a 58.2% vote, however, shutting down any talk of investment in nuclear energy . At a press conference, Swiss Energy Minister Doris Leuthard said “After six years of debate in parliament and at committee level, a new chapter in Switzerland’s energy policy can begin. But there is still a lot of work to do.” Related: Tunnel collapses at America’s most contaminated nuclear waste facility Energy Strategy 2050 mandates that general licenses provided for nuclear power plants (which presently provide 38% of the country’s energy) will no longer be sold, beginning in 2019. Additionally, when existing nuclear power plants reach the end of their lifespan, they will be closed and not replaced. The reform also aims to reduce per capita energy consumption by 16 percent within the next three years, and by 43 percent by 2035. Energy Strategy 2050 intends for electricity consumption to decline by 3 percent in 2020 and 13 percent in 2035. This will be managed by increasing the output of solar , wind, biomass, and geothermal energy. Supporters of the law say that investing in renewables will make Switzerland less dependent on energy imports. At the same time, the country will maintain its highly supply standard. Activists are also celebrating the fact that by phasing out investments in nuclear energy, the environment and future generations will undoubtedly benefit. Via Swiss Info Images via Pixabay

Architect designs solar-powered research center to save dying Lake Chad

Comments Off on Architect designs solar-powered research center to save dying Lake Chad

Lake Chad in Africa spanned over 770,000 square miles in 50,000 B.C., according to Cameroon -based architecture firm Hermann Kamte & Associates (HKA). But over the centuries it has shrunk, dwindling to a mere 1,544 square miles in 2001. HKA hopes to use architecture to jumpstart regeneration of the dying lake in the form of a desalination and research center called The Forgotten – Dead or Alive. The center would begin a process that would eventually be handed over to nature . The first humans made their home near Lake Chad, according to HKA, but this body of water is in danger of disappearing forever. It could die out in this century if no steps are taken to preserve it. Lake Chad – bordered by Cameroon, Chad, Nigeria, and Niger – is vital to the health of the region; HKA says its disappearance would impact over nine million people nearby, and indirectly, 30 million people in the region. Related: Green-roofed wooden tower in Lagos maximizes daylight and natural ventilation So they designed a center to help keep the lake alive. The self-sufficient Limnology Center would offer a location for researchers to study Lake Chad and the surrounding region. A desalination center onsite would actually connect the lake to the Atlantic Ocean via pipelines , which would transport water from the ocean. The desalination center would treat the saltwater so it could be reused as fresh water to help restore Lake Chad and provide a source of water for people in the region. HKA designed the center to have an amphibian-like form to blend in with the lake surroundings. They envision three stages to help revitalize the lake, beginning with the center and then slowly transitioning the job over to nature. Construction of the pipelines and lake research would take place between 2016 and 2026. In 2020 trees and vegetation will be planted around the lake. The greenery will eventually take over the job of regeneration; in 2080 pipelines will stop bringing in Atlantic Ocean water as natural regeneration takes over thanks to a thriving woodland. + Hermann Kamte & Associates Images courtesy of Hermann Kamte & Associates

Daan Roosegaarde introduces smog-sucking, air-cleaning bikes

Comments Off on Daan Roosegaarde introduces smog-sucking, air-cleaning bikes

Daan Roosegaarde has been touring China with his Smog Free Project , showcasing the Smog Free Tower and encouraging people to find innovative solutions to address air pollution . He’s not out of ideas yet though; he’ll add to his tour with new smog-sucking bicycles . These bikes could work much like his Smog Free Tower does, absorbing dirty air , cleaning it, and pouring it back out as fresh air. Biking in a city polluted by smog isn’t healthy, so people are less inclined to ditch their cars and opt for a bicycle. Roosegaarde envisions an answer to that problem in a bike that can inhale dirty air, clean it, and pump it out around a cyclist. Related: China’s crazy smog-sucking vacuum tower might actually be working In a statement, Roosegaarde said, “ Beijing used to be an iconic bicycle city. We want to bring back the bicycle as a cultural icon of China and as the next step towards smog free cities.” The studio says the concept aligns with growing interest in bike sharing programs in China – like Mobike , which has over a million shareable bicycles in the Beijing area. There’s still a long way to go to slash pollution and traffic in the country’s capital, but the smog-sucking bicycle could offer a creative approach to the problem. The Smog Free Bicycle found its beginnings in a Studio Roosegaarde-hosted workshop at contemporary art museum M Woods in Beijing, featuring Professor Yang of Tsinghua University and artist Matt Hope, who worked on an idea for an air-filtering bike around four years ago . According to Studio Roosegaarde, the new smog-sucking bicycle is “currently in the first stage and is intended to become a medium for smog free cities, generating clean air by pedaling, and creating impact on the larger urban scale.” + Studio Roosegaarde Images via Studio Roosegaarde and Wikimedia Commons

The past and the future coexist in this daylit house in Nara, Japan . Tokyo-based architecture studio ASSISTANT designed the house as a cluster of small buildings for an elderly couple who places great value on preserving memories. The result is a steel-framed structure that was built in several different locations and then assembled on-site to create several overlapping spaces. Local carpenters in Aomori built the main quarters of the house using locally available materials . The project was initially installed as part of the “Kime to Kehai” exhibition at the Aomori Contemporary Art Centre. After the exhibition, the team disassembled the structure and loaded it on a truck to transport it to Nara, where it was reassembled as the House of 33 Years. Related: Renovated Vietnamese home ‘sewn’ together with intricate steel threads Students at the Sendai School of Design built the rooftop pavilion as an homage to Philip Johnson’s Ghost House.

Dakota Access pipeline springs first oil leak – before completion

Comments Off on Dakota Access pipeline springs first oil leak – before completion

Before the Dakota Access Pipeline (DAPL) was even completed, it suffered its first leak. On April 6, the $3.8 billion project spilled 84 gallons of crude oil at a South Dakota pump station, enraging members of the Standing Rock Sioux tribe and other activists who protested its development for nearly one year. The Guardian reports that the leak was quickly contained and cleaned. However, critics of the spill say that the environmental travesty could have been prevented had state officials listened to concerned members of the Standing Rock Sioux tribe and those who support them. The pipeline was in its final stages of preparing to transport oil when the leak occurred. Beginning in April of 2016, thousands of people gathered near Cannon Ball, ND, to protest the DAPL ’s development. The main concerns continue to be that its construction could contaminate the Missouri river and that a portion of land the DAPL runs through was promised to the Standing Rock Sioux in an 1851 treaty. Though the Obama administration halted the DAPL’s development in December of 2016, President Trump ordered it to resume shortly after his inauguration. Activists were forcibly removed from the protest grounds. Jan Hasselman, a lawyer for the Standing Rock Sioux tribe, said, “They keep telling everybody that it is state of the art, that leaks won’t happen, that nothing can go wrong. It’s always been false. They haven’t even turned the thing on and it’s shown to be false.” “It doesn’t give us any pleasure to say, ‘I told you so.’ But we have said from the beginning that it’s not a matter of if, but when. Pipelines leak and they spill. It’s just what happens,” she added. The Standing Rock Sioux tribe, which has fought Energy Transfer Partners and the U.S. government in court, argues that the project requires a full environmental study to assess the risks. Because President Trump has financial ties to the oil company, however, it is unlikely such an assessment will be conducted. Standing Rock Sioux tribe chairman Dave Archambault II said the spill is just one more sign the courts should intervene. “Our lawsuit challenging this dangerous project is ongoing, and it’s more important than ever for the court to step in and halt additional accidents before they happen – not just for the Standing Rock Sioux Tribe and our resources but for the 17 million people whose drinking water is at risk,” he said in a statement. Related: Major oil spill 150 miles from DAPL protest validates Standing Rock concerns Neither the company nor the state have made a public announcement about the spill . According to Brian Walsh, an environmental scientist with the South Dakota department of environment and natural resources, this is because the spill was relatively minor as it was caused by a mechanical failure at a surge pump. “It’s not uncommon to have a small release at a pump station,” said Walsh, adding that the company responded immediately and cleaned up the liquid petroleum.
