Data from the National Center for Energy Control (CENCE) showed that Costa Rica went 257 days on almost 100% renewable energy.

According to the Latin Correspondent, the Costa Rican Electricity Institute (ICE) reported that 98.82 percent of the electricity generated for domestic use came from renewable sources such as wind, geothermal, solar, biomass, and hydroelectric plants. Only 1.18 percent of generated electricity came from fossil fuels, used as a backup in the events of unfavorable weather conditions.

“The decline in oil imports has positively impacted electricity prices, as well as the expansion strategy and exchanges with the regional electricity market,” said ICE CEO Carlos Manuel Obregon. Luis Pacheco, ICE manager, added that their projections show the trend continuing in 2016.

ICE announced in March that the country’s initial target is to survive on 97.1 percent of clean energy.

Costa Rica has long been a leader in using renewable sources for electricity, prior to world leaders focusing on other sources of energy as a result of climate change.

Earlier this year, ICE announced that the country ran on 100 percent clean electricity for the first 75 days of the year. This was considered a huge feat by the international community, but more importantly, it was good news for consumers as electricity prices were cut by 7 to 15 percent.

The feat can be attributed to rainfall that Costa Rica received in the first part of the year, as the country mostly relies on the hydropower generation.

Costa Rica is committed to be carbon-neutral come 2021.

Total global solar PV capacity will increase by 27% in 2015, despite policy changes says report

global solar PV capacity

Total global solar PV capacity will increase by 27% in 2015 – Global solar PV capacity rises to 223GW despite policy changes says report. Image source.

A new report predicts that the global cumulative installed capacity for solar PV energy will hit 223.2 GW by the end of this year compared to 2014’s 175.4 GW.

And this, says the study, is despite the anticipated declines in the annual installations of several key countries.

According to Power Engineering, the report from research firm GlobalData, states that China will remain the world’s largest market for annual solar PV installations in 2015, adding around 17.6 GW this year.

The US will follow with almost 8.2 GW of additions while India will witness strong demand in its solar PV market thanks to growing policy and political support.

However, despite this overall growth, Ankit Mathur, GlobalData’s head of power, said adjustments in the government policies of Germany and Japan will see their annual solar PV installations fall this year.

“After amending its renewable energy law in August 2014, Germany is expected to attain an annual installed capacity of around 1.8 GW in 2015 and will fail to hit the annual solar PV installation target of between 2.4 and 2.6 GW. This is due to ongoing feed-in tariff digressions, along with the €0.0617 [$0.0688] surcharge on self-consumption in 2015.”

Mathur added that Germany “is implementing initial measures to move away from expensive renewable energy subsidies and towards a reverse auction system by 2017. Two rounds of auctions took place in Germany earlier in 2015, with the third round expected to take place in December.”

Similarly, Japan’s lucrative solar PV policies, which had been attracting strong investment in recent years, have seen cuts in 2015 that will mean a reduction in installed capacity additions, compared with 2014’s record-breaking figure of 10 GW.

Mathur said: “With the arrival of the first solar PV FiT cut in April 2015, Japan’s FiT level decreased from $0.27 per kilowatt hour in 2014 to $0.24 per kWh, and further to $0.22 per kWh from July 1, 2015.

“These cuts, put forward by the Ministry of Economy, Trade and Industry, ended the premium rates for solar PV, and were triggered by a maturing market that has seen the cost of solar operation and maintenance fall.”

MidAmerican is building the tallest concrete wind turbine tower

MidAmerican Energy is planning to build the tallest land-based wind turbine in the country in Iowa.

According to todesmoinesregister.com, the Des Moines-based power company will get the added height by building the wind turbine tower from concrete instead of steel, a first for the company. The extra 100-plus feet enables the turbine to capture more wind energy, the utility said.

“Generally speaking, the higher the altitude, the greater the wind resource available,” said Mike Gehringer, MidAmerican’s vice president of renewable energy.

The 2.3-megawatt concrete tower turbine at the Adams County wind farm will measure 377 feet from ground to hub, compared to 263 feet for most of the turbines in use at other MidAmerican wind farms.

With blades extended, the turbine will reach a height of 554 feet, making it about as tall as the Washington Monument.

The utility has contracted with Siemens to supply and construct its new concrete tower design

Siemens and MidAmerican see the prototype as the model for other concrete turbine towers at future wind farms. It would open up “low-to-medium wind resource areas of Iowa for future wind development,” Gehringer said.

The company said the process of building a concrete tower is quite different from the process used to construct turbines with steel towers. “Instead of building the tower sections in a factory and transporting them to the site to be fitted together, crews pour the concrete in segments and manufacture the tower onsite,” Gehringer said.

The concrete turbine is one of 64 wind turbines planned for MidAmerican’s Adams County wind farm. Construction is underway on the 154-megawatt project, and all turbines are scheduled to be erected by the end of 2015.

Siemens sourced the concrete formwork from EFCO Corp. in Des Moines and supplied the wind turbine blades for the entire Adams project from the Siemens blade factory in Fort Madison.

Leonardo DiCaprio’s company is making ethical diamonds using solar energy

Diamond Foundry, launched last week, was founded by Leonardo DiCaprio with the goal of reinventing the $100B diamond industry from “mine to finger” by setting a new standard for social and environmental good.

“I’m proud to invest in Diamond Foundry Inc. — reducing the human and environmental toll of the diamond industry by sustainably culturing diamonds without the destructive use of mining,” says Leonardo DiCaprio

According to diamondfoundry.com, the founding team of M.I.T., Stanford, and Princeton engineers previously developed pioneering breakthroughs in solar power technology – and had a hunch that techniques used to harness the energy of the sun could also be used to make a better diamond, atom by atom.

“We started by studying the laws of nature. Diamonds are born from a fiery heat, so we set out to create a plasma of unprecedented energy density. We coded software to run tens of thousands of physics-based simulations. In a warehouse just south of San Francisco, we built novel plasma reactors with hundreds of individually precision-engineered parts. Then, we formed plasma as hot as the outer layer of the sun,” says the Diamond Foundry.

The researchers discovered a plasma by which they can attach atoms to an earth-extracted diamond and grow it in size. One by one, the atoms stack on top of a thin slice of earth diamond and extend its unique crystal structure. Layer by layer, it grows into a pure, cultured, jewelry-grade diamond of larger size. After this step, the team slice off and reuse the original any number of times.

“We are now able to produce stunning diamonds in our San Francisco foundry. Each is a unique crystal of pure diamond, just like industrially mined diamonds but morally pure as well.

We use solar power credits to reduce our carbon footprint to zero, and we guarantee the characteristics and provenance of our diamonds: each is born at our foundry in California. The ultimate diamond: 100% pure. 100% ethical. Each unique.”

Moving to renewable energy would create millions of jobs, study finds

Moving toward renewable energy would be a boon to the economy, studu says. Image source

A new report has found that transitioning to a clean energy economy would be an economic boon to the United States, increasing employment, reducing costs to consumers, and benefiting investors.

The report, from NextGen Climate America, showed that investment in efficiency, renewable sources of electricity, and fuel switching — such as moving from fossil fuel-powered cars to electric vehicles — would add a million jobs by 2030, and roughly 2 million jobs by 2050, while increasing GDP by $290 billion and improving household income. The researchers looked at scenarios that would reduce emissions by 80 percent below 1990 levels.

“While addressing climate change is one of our greatest challenges, it is one of our greatest opportunities to build the economy,” Tom Steyer, co-founder of NextGen and billionaire climate activist (and a board member of the Center for American Progress), said on a call with reporters Monday.

The construction industry, in particular, could see a huge bump in jobs — to the tune of 1.2 million more in 2050 than under the business-as-usual scenario. That’s because it will take a lot of people to build the wind farms, install the solar panels, and retrofit the buildings needed to reduce America’s dependence on fossil fuels.

Efforts to lower emissions are often subject to the criticism that they will hurt the economy, even though actual examples of programs have shown that efficiency and clean energy programs can actually boost economic factors like household disposable income.

“The go-to argument against [climate action] is that it’s bad for the economy and it’s a job killer,” Steyer said. This report shows otherwise. Steyer also pointed out that in the last few years, jobs in the solar industry have grown 20 times faster than the rest of the economy.

In addition, the so-called reference case — a general economic forecast — did not take into account the potential costs of not addressing climate change. Recent reports have shown climate change poses a significant financial risk.

According tothinkprogress.org, the report studiously stays away from telling policymakers how to get to 80 percent less emissions. Rather than policy recommendations, the researchers took a feasibility study and used it to build out the economic impacts.

The researchers used a 2014 report, Pathways to Deep Decarbonization in the United States by Energy and Environmental Economics, which looked at whether it was technologically feasible to reduce carbon emissions significantly enough to avoid 2°C warming.

Economist Jeffery Sachs told reporters it was critical to first determine where we want to go, and then tailor policies to achieve those end goals.

“Too often our national policy conversation jumps straight to the question, ‘Is it a tax? Is it this or that?’ Whereas what this report does, much better, in my opinion, is to show here’s where we want to go,” Sachs said.

Overall, the report painted an optimistic picture of the economy under a clean energy scenario. It’s worth noting, though, that the gains will not be across the board. Job growth in two of the nine regions was expected slow under the low-carbon scenarios. Those two regions — which include roughly the area from Montana to Texas, a fossil fuel heavy swath of the country — would have slower job growth.

That means that as the country does develop policies to achieve these goals, it will likely need to dedicate resources — educational and economic — to areas that will have a harder time getting off fossil fuels.

“To help them adapt we need to provide dedicated new resources for economic diversification, job creation, job training and other employment services for workers and communities affected by job losses at coal mines and coal-fired power plants,” the authors said.

Jobs notwithstanding, all regions were found to see increases in disposable income.

Trina Solar, a global leader in photovoltaic modules, solutions and services, today announced that its State Key Laboratory of PV Science and Technology of China has set a new world record for a high-efficiency p-type multi-crystalline silicon solar cell.

According to a press release, the record-breaking p-type multi-crystalline silicon solar cell was fabricated on a high-quality mc-Si substrate with a process that integrates advanced Honey Plus technologies including back surface passivation and local back surface field.

The 156×156 mm2 solar cell reached a total area efficiency of 21.25%. The result has been independently confirmed by the Fraunhofer ISE CalLab in Germany. This efficiency record breaks the previous 20.76% efficiency world record for mc-Si solar cells also established by Trina Solar one year ago. To set this new record, only low-cost industrial processes which can be easily integrated into large-volume production were used.

“We are very pleased to announce the new efficiency results achieved by our scientists and researchers at the State Key Laboratory of PV Science and Technology. To the best of our knowledge, this is the first time ever that a multi-crystalline silicon solar cell has been able to achieve a conversion efficiency of over 21%,” said Dr. Pierre Verlinden, Vice-President and Chief Scientist of Trina Solar.

“This exciting result shows that the development path toward higher efficiencies continues to be bright, even for silicon. Our aim is to continuously integrate innovative technological developments to improve the efficiency and lower the cost of our PV products. This technology advancement in efficiency will strengthen our leadership in the PV industry and allow us to continue providing affordable solar power to the world.”
