New Zealand’s new prime minister has ambitious goals to seriously slash carbon emissions . Jacinda Ardern, who became prime minister in late October, wants to transition the grid to 100 percent renewables in less than 20 years. Her ultimate goal for New Zealand is zero carbon emissions by 2050. New Zealand’s 4.7 million people already obtain over 80 percent of electricity via sustainable sources, according to Bloomberg . But Ardern – now the world’s youngest female leader – seems to think they can do even better. She wants the country to move over to obtaining electricity completely from renewable energy by 2035. Related: New Zealand river world’s first to obtain legal status as a person The move won’t be without its challenges. New Zealand generates around 60 percent of their power from hydropower , according to 2016 figures. But when dry conditions cause lake levels to drop, gas and coal have helped out. Without those fossil fuels , electricity consumers could experience price hikes. But the country still has made a lot of progress towards the ambitious goal; in the winter of 2016, renewable energy generation actually peaked at 93 percent, according to Bloomberg. Ardern hasn’t put out full details of her plan to get New Zealand to a carbon-free status. She has suggested an independent commission to help meet the 2050 goal. New Zealand’s independent advisory body Productivity Commission has an inquiry into transitioning to a low carbon economy. Greenpeace New Zealand climate and energy campaigner Amanda Larsson told Bloomberg Ardern “must prioritize closing down coal, putting a moratorium on new fossil fuel plants, building more wind infrastructure, and opening the playing field for household and community solar .” Contact Energy chief executive officer Dennis Barnes also pointed to solar – and batteries and electric vehicles – as technology that could help New Zealand move towards a greener future.

New EV charging system lets Nissan Leaf owners sell power back to the grid

Comments Off on New EV charging system lets Nissan Leaf owners sell power back to the grid

UK residents who plan to purchase an electric vehicle (EV) next year should hold out for a Nissan Leaf. Energy company Ovo has partnered with the automaker to allow anyone with a garage to receive a special charger that facilitates a “vehicle-to-grid” energy exchange. During off-peak hours, when electricity costs are low, the charger will power up batteries, and switch back to charging up a home or even selling energy back to the grid during peak hours. Essentially, this means EV owners may never have to pay to charge their eco-friendly car. In off-peak hours in the UK, electricity costs approximately 5 cents a kilowatt ($0.07). At peak hours, that increases to as much as 25 cents. “In other words, the value of the electricity that’s stored in the battery goes up by a factor of five,” said Stephen Fitzpatrick, CEO of Ovo. “It provides an economic benefit for electric vehicle owners, so they get more use of out of the vehicle that they’ve got parked in the driveway.” By no means is the Nissan Leaf inexpensive. The brand-new car costs £26,490, or $35,064. However, by taking advantage of Ovo’s new program, car owners could save thousands of dollars in energy costs in the long-term. According to Fitzpatrick, the “vehicle-to-grid” technology is not complicated, which is why “other electric car manufacturers are looking at this.” He said, “If it lowers the cost of vehicle ownership, if it lowers the cost of driving the vehicle per mile, I think there will be a lot of consumer demand for it, and that will translate into agreement on technical standards with other car manufacturers.” As FastCompany reports, using the battery automatically in this way — instead of leaving it plugged in, is also better for its battery life. Related: 2018 Nissan Leaf debuts with 150-mile driving range for just 30k By 2021, there will be approximately 1 million electric cars on the road in the UK. If every single vehicle were to be plugged in at the same time, there would be a demand for seven gigawatts of power — or the equivalent of 10 power stations. On the contrary, if the cars were plugged in and charging at a peak time, the power stations would be obsolete. Clearly, technology such as this is needed. And, not only will “vehicle-to-grid” tech help solve the challenge of providing enough electricity to the growing number of EVs, it will also save vehicle owners money. “The flexible use of car batteries is a perfect complement for renewable generation,” said Fitzpatrick. “You can imagine as we see more electric vehicles on the road, we can have more and more renewable generation without compromising the grid stability…renewable energy and electric vehicles are the perfect complement, just like oil and the internal combustion engine.” Via FastCompany Images via Pixabay , Nissan Leaf

Comments Off on This new energy concept from Sweden can make any building net zero

A new Swedish energy concept can turn any building into a net zero energy structure. Pioneered by Malmö-based company Innenco , the concept utilizes a building’s thermal mass to drastically reduce energy use by around 85 percent. With their active elements systems, heat pumps, chillers, and adding solar panels , Innenco can bring new or existing buildings to net zero energy consumption. Inhabitat spoke with CEO and founder Jonathan Karlsson to find out more. Innenco, which stands for innovative energy concept, dramatically slashes a building’s energy use. Karlsson told Inhabitat, “Our vision is to create possibilities to make new net zero constructions in an efficient way, giving everyone the capability to do so.” Their technology changes how a building operates for vastly improved energy efficiency . Related: California city could become the first Zero Net Energy city in the U.S. It starts with their active elements system: pipes are integrated into the frame construction to utilize a building’s thermal mass. Adding heat pumps and chillers to the system allows Innenco to get four to six times greater efficiency in heating and cooling . At this point they’re able to reduce energy use by 85 percent, so to cover that last 15 percent, they install Innenco Quantum Solar panels. “This makes an investment in solar cells much lower than a traditional system, and we can get net zero for a really cost-efficient investment,” Karlsson told Inhabitat. Buildings with the Innenco system installed tend to maintain a temperature of around 22 degrees Celsius, or around 72 degrees Fahrenheit. Innenco has already seen their concept work in the real world. They’ve installed their system in homes, offices, schools, and industry premises. Karlsson said they were excited to discover they could utilize a really high rate of thermal mass in industry buildings, and think their concept could translate well to skyscrapers . They’ve worked in Sweden, the Czech Republic, Spain, and the Netherlands, with projects coming up in Turkey and the United Arab Emirates. They provide maintenance, and their energy concept can be installed as new buildings are built or integrated in old ones. Karlsson said sustainability projects should deliver social, environmental, and economical benefits, all three of which Innenco aims to offer with their concept. “Reducing carbon dioxide emissions is a really high goal for us,” Karlsson told Inhabitat. “It’s the climate condition; it’s really necessary to figure out how we can help the planet.” Innenco hopes to introduce their energy concept to other markets too, such as the United States.

Comments Off on India aims to bring electricity connections to 40 million households

Millions of homes in India lack electricity . Prime minister Narendra Modi hopes to change that with his Power For All By 2019 plan. Under the scheme, around 40 million households could obtain electricity connections – with the poor receiving them for free. Low income households could finally receive electricity in India. While people won’t get power for free under the Power For All plan – they’ll need to pay for electricity they consume – they could get a free connection. Homes will be connected to the closest electricity pole by a service cable, and the government will install an energy meter and wiring so homes can charge mobile phones and obtain light from an LED bulb. Related: India cancels plans for coal power stations as solar prices hit record low Homes in rural areas that can’t easily be connected to the grid will receive solar power packs of 200 to 300 watts and a battery pack. They’ll also get five LED lights, one DC power plug, and one DC fan, according to BloombergQuint. In addition, the government will provide maintenance and repair for five years. The idea isn’t completely new; Anil Razdan, former power secretary, told BloombergQuint it’s a decade old, and they’ve been working to electrify villages, but now, “after having spent tens of thousands of crore, we’ve finally decided to take it to every home.” Some households in the past couldn’t afford initial connection charges, and under the new plan, such homes could get connections for free. India will need around 28,000 more megawatts (MW) for the plan, according to BloombergQuint. Clean energy has been soaring in the country, according to a statement from Modi , which said in the past three years, renewable energy capacity has nearly doubled. Solar power capacity grew by almost five times. The government’s goal is to produce 175 gigawatts of clean power coming from wind, solar, and hydro by 2022.

Puerto Rico electricity crisis sparks interest in renewable energy

Comments Off on Puerto Rico electricity crisis sparks interest in renewable energy

Hurricane Maria has left swaths of Puerto Rico without power – and millions of people could have to go without electricity for months . The storm’s devastation has stirred new interest in obtaining more energy from clean sources like solar or wind . Energy experts say increasing renewables and transitioning from centralized grids to microgrids could boost resilience as Puerto Rico and other Caribbean islands weather storms. CARICOM, a Caribbean nation consortium, already hoped to hit 47 percent renewable energy by 2027. The recent hurricanes could act as a motivation to work for that goal. Caribbean countries in the past have relied mostly on imported fossil fuels , which are expensive both for the islands and for the environment . And storms can cripple power lines. Related: Puerto Rico could be without electricity for months due to Hurricane Maria There is an alternative, according to The Washington Post. Renewable sources, coupled with battery storage , powering small grids could offer more resiliency. Fossil fuels would offer backup—at least initially until battery storage becomes more affordable. The microgrids could be connected to a main grid but could also be isolated. With this new setup, the Caribbean could benefit from trade winds and solar panels. According to renewable energy expert Tom Rogers, who works at Britain’s Coventry University, solar systems in the tropics can “generate over one and a half times more than exactly the same PV system” installed in a location with a higher latitude like Europe. Rogers told The Washington Post, “You look at islands like Dominica, Anguilla, and other islands affected by the recent hurricanes, I’ve spoken to a couple of the utilities, and they say they would prefer to rebuild using distributed generation with storage, and just trying to reduce the amount of transmission lines. Because that’s where their energy systems fail. It’s having these overhead cables.” Via The Washington Post Images via Sgt.

MIT researchers explore ancient firebrick technology to store energy

Comments Off on MIT researchers explore ancient firebrick technology to store energy

Firebricks – or bricks made with clay able to endure temperatures of 1,600 degrees Celsius – have been around for at least 3,000 years. Now Massachusetts Institute of Technology (MIT) researchers are revisiting this ancient technology to potentially help us transition from fossil fuels to renewable energy . The researchers worked out a scheme where excess electricity , generated when the wind is blowing or sun is shining, could be converted into heat and stored in the firebricks for later use. The firebricks technology has existed since the time of the Hittites, according to MIT researchers, who want to draw on this old technology to help make carbon-free power sources competitive with fossil fuels. Right now, with solar and wind power , electricity prices can collapse to near zero when there’s high wind or solar output, making those clean energy installations unprofitable unless companies can store power. Related: Google wants to solve renewable energy storage with salt and antifreeze Their system, called Firebrick Resistance-heated Energy Storage, or FIRES, costs between one-tenth and one-fortieth as much as pumped hydroelectric systems or batteries . It works like this: electric resistance heaters convert that excess electricity to heat, which would be stored in a large mass of firebricks. If the firebricks are inside an insulated casing, they can store that heat for long periods of time. The heat could either be utilized for industrial processes or converted back to electricity later. Regis Matzie, retired Westinghouse Electric Chief Technical Officer, wasn’t involved with the research but told MIT the way electricity prices are determined in America yields to a “skewed electricity market [that] produces low or even negative prices when a significant fraction of electrical energy on the grid is provided by renewables.” He said FIRES could offer an innovative solution, but a demonstration would probably be needed to see if the method is indeed economical. The Electricity Journal published the MIT research online the end of August. The next step will be setting up full-scale prototypes in the real world, which lead author Charles Forsberg said could occur in 2020. He said they’re looking for the right customers – one example would be an ethanol refinery, since they use a lot of heat, located near a large wind farm .

Comments Off on Three hurricanes form in the Atlantic for the first time since 2010

While Hurricane Irma barrels through the Caribbean towards the United States mainland, another two potentially powerful storms are waiting in the wings. Following closely behind Irma, one of the strongest hurricanes recorded in the Atlantic, are Tropical Storms Jose and Katia. The presence of these storms marks the first time since 2010 that three active hurricanes have formed in the Atlantic. In what may prove to be one of the most active on record , the 2017 Atlantic hurricane season has already demonstrated the unpredictable and explosive power of storms in the age of climate change . Jose, like Irma, is known as a Cape Verde hurricane for its origins in the far eastern Atlantic , near the island nation of Cape Verde off the coast of Africa . However, it is unlikely that Jose will follow Irma’s path nor will it likely be as powerful. Jose is expected to spin towards the open ocean and become a Category 3 hurricane, though it is not expected to travel over any land area. Related: Harvey forces National Weather Service to add new color to its rainfall map Katia is more closely related to Harvey, in that it too became a hurricane in the warm waters of the southern Gulf of Mexico. Despite its shared birthplace with the devastating hurricane that made landfall near Houston , Katia is expected to travel close to Mexico . It is currently nearly 200 miles northeast of Veracruz, Mexico, near which a small portion of the coast is currently under hurricane watch. Although three hurricanes active in the Atlantic at the same time is unusual, it is neither unprecedented nor unrivaled. During the 1998 Atlantic hurricane season, four hurricanes, including Hurricane Georges which caused major damage in Haiti and the Dominican Republic , were active during the same period.

Comments Off on People in Denmark are earning up to $1,530 just by parking their EVs

What if you could get cash for parking your electric car ? Vehicle owners in Denmark have been able to do just that, bringing in around 1,300 Euros, or around $1,530, a year by feeding excess power back into the grid. Nissan Motor Company conducted trials in the country with Italy’s utility company Enel SpA to show how EV batteries could help ease constraints on the electrical grid. Nissan has run trials with over 100 cars throughout Europe, but so far only owners in Denmark have been able to earn cash by parking their vehicle and sending power to the grid . Using two-way charge points, owners have been able to rake in $1,530 annually, according to Nissan Europe energy services director Francisco Carranza. Related: Tesla is doubling its Supercharger network by the end of the year to 10,000 chargers Electric car owners in the United Kingdom could be next to score a payday – due to restrictions on accessing the market, Nissan needs to get up to 150 cars before people can earn money. Carranza estimates they could hit that number later this year. He told Bloomberg, “It’s just a matter of finding the appropriate business model to deploy the business wide-scale.” Electric car demand, expected to grow around the world, could place a strain on local electrical grid operators trying to figure out ways to balance demand. According to Bloomberg New Energy Finance, power consumption from cars will climb from around six terawatt-hours today to 1,800 terawatt-hours in 2040. The scheme of using car batteries to balance supply and demand could help grid operators while potentially allowing car owners to earn some extra money with minimal effort. According to a July 2017 Business Insider article , the Danish government recently cut back subsidies for electric vehicles and sales fell – at that point in 2017 a mere 182 electric cars had been sold in the country. But Denmark also has more EV charging docks than petrol stations. Via Bloomberg Images via Wikimedia Commons ( 1 , 2 )

Comments Off on Restorative Healing Gardens take over a concrete garage rooftop in L.A.

A healing green landscape has blossomed in the place of a former concrete plaza in Los Angeles. Local firm AHBE Landscape Architects transformed a concrete site atop a multi-level garage into the new Healing Gardens for Cedars-Sinai Medical Center. The unique, green roof -inspired system features four distinct gardens that promote healing, health, and well being for patients, hospital staff, and visitors. Since the site was located atop a building, AHBE had to develop a multi-layered landscape solution that would protect the existing building’s structural and mechanical integrity while accommodating four lushly planted gardens. “The Cedars-Sinai Healing Garden Plaza project presented several constraints that encouraged innovative thinking,” said Calvin Abe, FASLA, RLA, who led the project team. “The terraces had previously been unused for many years. We aimed to heal the epidermis of the complex by grafting a piece of living, breathing landscape above the existing parking decks.” The addition of the Healing Gardens is an extension of Cedars-Sinai Medical Center’s mission to prioritize quality patient care.

In contrast to the more active Garden of Whimsy, the shaded Blue Garden is designed for quiet meditation and features private nooks and small circular reflecting pools. The open Plaza Garden accommodates a variety of events with moveable and convertible furniture ; the space is complemented with textural plants such as agaves and succulents. The Education Garden features “adaptive natives” from non-U.S. Mediterranean climates and includes space for outdoor lectures, health fairs, and informal meetings. + AHBE Landscape Architects Images by @heliphoto.net
