We need to grow 50% more food yet agriculture causes climate change. How do we get out of this bind? The World Bank’s head of agriculture and food security speaks of a “frustrating lack of attention paid to agriculture” at the climate talks and calls for advances in climate-smart farming
Mark Cackler, 3 July 2015 (The Guardian)
“We are trapped in a vicious cycle: we will need to grow 50% more food by 2050 to feed 9 billion people but agriculture, which is paradoxically vulnerable to climate change, generates 25% of heat-trapping greenhouse gas emissions that lead to climate change. The more we grow using conventional methods, the more we exacerbate the problem. It’s time for a climate-smart agriculture but first we must address a few man-made problems…By definition, food production affects all countries, rich and poor, and it is hard to imagine any effective post-Kyoto climate change agreement that ignores 25% of the problem. So, we need a climate change agreement where agriculture is a big part of the solution, and delivers a triple win: higher agricultural productivity to feed more people and raise the incomes of poor farmers - especially women, greater climate resilience, and reduced greenhouse gas emissions…” click here for more
Discovery Brightens Solar's Future, Energy Costs to Be Cut
July 2, 2015 (Reuters via NBC News)
“Scientists in Switzerland…[have] a cheaper, solar technology that splits water molecules to [make it cheaper to] create clean-burning hydrogen fuel…but a simple version won't be available for average citizens for at least 10 years…Splitting water molecules to create hydrogen allows the sun's energy to be more easily stored to generate electricity or power clean cars…Previous solar hydrogen technologies were too expensive to commercialize, scientists from the Ecole Polytechnique Federale de Lausanne said…The new solar panel looks similar to the traditional version mounted on rooftops, except sunlight first passes through a thin layer of water contained inside the device. Tungsten diselenide, a non-toxic chemical, acts as a photocatalyst and is critical for using the sun's energy to split water into oxygen and hydrogen.” click here for more
Viaducts with wind turbines, the new renewable energy source

“Wind turbines could be installed under some of the biggest bridges on the road network to produce electricity…[according to European researchers using Juncal Viaduct in Gran Canaria of the Canary Islands] as a reference. This concept could be applied in heavily built-up territories or natural areas with new constructions limitations…[because] the wind blowing between the pillars on this kind of infrastructures can move wind turbines and produce energy…Results confirm that each viaduct presents specific energy possibilities and wind potential. In the Juncal Viaduct case, the evaluated power would be about 0,25 MW per wind turbine. So, with two turbines, the total power output would be 0,5 MW, which is classified in the medium-power range…” click here for more
Renewable Energy from the Ocean One Step Closer with Completion of Biowave Construction

"The next shale": How solar is poised to transform America's energy markets; A new study says the solar boom is coming faster than many think
Herman K. Trabish, February 19, 2015 (Utility Dive)
A lot of people didn’t see the shale oil and gas revolution coming, and now a new report says many are failing to anticipate a coming energy explosion that will transform the energy sector to a similar extent.
Plummeting module prices and rising module efficiencies are driving a solar boom so big it may face only one obstacle: Its own success.
“The comparison is that the magnitude of the impact solar can have on the market is similar to the impact shale gas has had,” said Wood Mackenzie Research Director Prajit Ghosh. “The economics of solar is already competitive in many parts of the U.S. and that will only get better.”
There are many parallels between the energy revolution created by shale resource development and what is now happening in solar, said Ghosh, lead author of the consultancy's recently-released report, "Solar: The Next Shale?" An example is that rigs became more productive in shale in the same way that module efficiencies are driving the solar boom.
The comparison is more qualitative than quantitative but both the shale revolution and today’s solar boom are technology driven, Ghosh added.
A Net Cost Analysis verifies solar’s value
Dissatisfied with levelized cost of energy (LCOE) studies showing solar’s competitiveness, Ghosh’s Wood Mackenzie team worked up a Net Cost Analysis (NCA) for comparison.
“LCOE doesn’t account for the fact that solar only produces energy during the day when there is no cloud cover,” Ghosh explained. “It doesn’t account for the revenue side.”
The Wood Mackenzie team created an annual revenue model for all U.S. and Canadian transmission load pockets that included a full range of factors, including varying supply-demand profiles, solar and wind resource profiles, and gas supply profiles. It then created annual revenue for a specifically defined solar facility at a known cost.
The difference between the revenues and the cost in the NCA confirmed LCOE analyses of solar’s rapidly expanding price competitiveness. In larger scale solar, 19 states will be at grid parity and competitive with natural gas generation by 2020 and 38 states will be there by 2030, according to the study. By 2025, states will be approaching grid parity in residential rooftop solar as well.
“An NCA for California solar shows the economics went from no-reason-to-build in 2009 to 10% of peak solar market share in 2014 and 2015 that approaches 14% to 15% in some months,” Ghosh said.
How solar displacing gas could stunt solar's growth
The NCA also showed how solar threatens solar’s growth.
“The regulatory support for shale exploration was in place to accommodate the impact of shale gas,” Ghosh said. “The power market structures are not.”
As the cost of solar falls, due to economies of scale and efficiencies, more is installed. With this increased market penetration, solar both displaces gas – which takes market share away – and also decreases the price the market pays for gas as capacity, Ghosh explained.
“This is not just a forecast, it is actually happening,” he said, noting the drastic drop in solar’s net cost curve and the rising gas cost curve shown in the Wood Mackenzie study. In particular, natural gas revenue in the high-price capacity market is lost.
“The economic incentive for new gas plants is no longer there,” Ghosh said. “But to integrate more solar, the market has to have something to run when solar is not available.
There either must be a technology, like battery storage, or an incentive to build flexible natural gas, like California’s flexible resource adequacy product.”
Accommodating such integration costs will either diminish the solar value proposition or impede growth, Ghosh believes. The more likely outcome will be a slowed pace of growth as integration costs are socialized. Grid operations and infrastructure will be affected. And other technologies, like wind and battery storage, could be factors.
“It depends on the market,” Ghosh said. “In ERCOT, the cost of the transmission build out to support wind was socialized. And there are a lot of mutual benefits in solar and wind profiles. In other markets, there might be a generally good profile showing wind could back up solar but it might not be a perfect correlation.”
Solar's biggest threat: Poor rate designs
In distributed and rooftop solar, Ghosh said, the economics are not as clear as in large scale solar because of many nuances and varying incentives.
The expanding battle in states over net energy metering (NEM) and rate designis a central question. Retail rate NEM was introduced in the 20th century as a convenience, not a calculation. It was intended to grow solar and it did.
But as rooftop solar owners’ electricity bills go down, their payments for bill infrastructure charges are reduced proportionally, Ghosh explained. “As solar rooftops proliferate, some utilities and regulators say those costs are being shifted to non-solar-owners.”
As a result, there is now much anti-NEM legislation and rate design review that will be decided in 2015, he said. “Watch those cases to know how the economics of rooftop solar will go.”
If utilities are successful at implementing rate design changes that capture fixed charges, it could curtail economic rooftop solar, Ghosh said. “But 20th century rate design with net energy metering does not account for the fixed cost in an appropriate manner and that rate design has to be changed.”
If the cost is not paid for appropriately, the problem multiplies, he said. “As solar gets more economic and more customers move away from the grid, it could cause a rate increase loop. The more rates increase, the more customers will want to leave. And it gets worse and worse for the utilities.”
Kicker: More cost reductions coming
There is every indication the cost of solar will continue to go down, Ghosh said. Module efficiency, the biggest driver of cost reductions, continues to improve. As prices get better, competition increases and that will push out market inefficiencies like value pricing and grow new opportunities like building integrated photovoltaics.
Finally, solar is not one technology. Just as thin film created competition that produced higher efficiency silicon-based modules, perovskite now may be a silicon replacement.
“It is not at all market ready,” Ghosh said. “But its efficiency has increased from 2% to 20%, a learning curve we have not seen historically. Given the rate of change of these technologies, we have to pay attention.”

Offshore Wind in Europe; Walking the tightrope to success
March 2015 (Ernst and Young)
In a context of strong commitment on GHG emissions reduction and uncertainty on fossil fuel prices and energy security, the large-scale deployment of renewable energy capacity appears indispensable to Europe moving forward. Offshore wind energy represents a crucial component of the future European energy system:
• Offshore wind in Europe currently represents one of the most stable sources of renewable energy, with increased energy capture expected due to Europe’s leading position in offshore wind R&D.
• Offshore wind energy is expected to grow to 23.5 GW by 2020, tripling current installed capacity.
• Industry efforts to reduce capital and operating costs mean that offshore wind will become highly competitive by 2023 when compared to other sources of energy. LCoE could reach €90/MWh by 2030 as long as a continual stream of projects enters the pipeline.
• The policy framework for securing 27% renewables and 40% reduction in GHG emissions by 2030 is currently unclear. However, in an “Offshore Wind Scenario”, the installed capacity of offshore wind power could reach almost 65 GW by 2030, allowing wind energy to make up more than 25% of electricity generation in Europe.
• The “Offshore Wind Scenario” could also save Europe €18b each year on fuel imports in 2030. Applying the SCoE model to the “Offshore Wind Scenario” shows that it is possible to build a low carbon energy sector €4b cheaper than in a “Nuclear Scenario”. Compared with other energy mix scenarios, prioritizing offshore wind energy could create the most jobs in the energy sector, displace the most carbon, and would be cheaper for society than nuclear or conventional sources of energy.
Today’s needed actions for 2030
In order to secure Europe’s commitments to climate change, energy security and a low carbon economy, offshore wind should be considered as an important component to the power mix. Continued cost reduction and support from policy makers are necessary to maximize the potential of offshore wind resources and to realize the socioeconomic benefits of a fully industrialized and emerging sector. Several key priorities have been identified to address these challenges:
• Ensure a stable regulatory framework and define long-term policy schemes
• Improve access to finance for the offshore wind sector
• Ensure cost-effective grid investment and connection
• Address planning system issues
• Face supply and logistics challenges
• Support innovation and training, and enhance synergies to reduce costs

New Energy Outlook 2015
June 2015 (Bloomberg New Energy Finance)
By 2040, the world’s power-generating capacity mix will have transformed: from today’s system composed of two-thirds fossil fuels to one with 56% from zeroemission energy sources. Renewables will command just under 60% of the 9,786GW of new generating capacity installed over the next 25 years, and twothirds of the $12.2 trillion of investment.
• Economics – rather than policy – will increasingly drive the uptake of renewable technologies. All-in project costs for wind will come down by an average of 32% and solar 48% by 2040 due to steep experience curves and improved financing. Wind is already the cheapest form of new power generation capacity in Europe, Australia and Brazil and by 2026 it will be the least-cost option almost universally, with utility-scale PV likely to take that mantle by 2030.
• Over 54% of power capacity in OECD countries will be renewable energy capacity in 2040 – from a third in 2014. Developed countries are rapidly shifting from traditional centralised systems to more flexible and decentralised ones that are significantly less carbon-intensive. With about 882GW added over the next 25 years, small-scale PV will dominate both additions and installed capacity in the OECD, shifting the focus of the value chain to consumers and offering new opportunities for market share.
• In contrast, developing non-OECD countries will build 287GW a year to satisfy demand spurred by economic growth and rising electrification. This will require around $370bn of investment a year, or 80% of investment in power capacity worldwide. In total, developing countries will build nearly three times as much new capacity as developed nations, at 7,460GW – of which around half will be renewables. Coal and utility-scale PV will be neck and neck for additions as power-hungry countries use their low-cost domestic fossil-fuel reserves in the absence of strict pollution regulations.
• Solar will boom worldwide, accounting for 35% (3,429GW) of capacity additions and nearly a third ($3.7 trillion) of global investment, split evenly between small- and utility-scale installations: large-scale plants will increasingly out-compete wind, gas and coal in sunny locations, with a sustained boom post 2020 in developing countries, making it the number one sector in terms of capacity additions over the next 25 years.
• The real solar revolution will be on rooftops, driven by high residential and commercial power prices, and the availability of residential storage in some countries. Small-scale rooftop installations will reach socket parity in all major economies and provide a cheap substitute for diesel generation for those living outside the existing grid network in developing countries. By 2040, just under 13% of global generating capacity will be small-scale PV, though in some countries this share will be significantly higher.
• In industrialised economies, the link between economic growth and electricity consumption appears to be weakening. Power use fell with the financial crisis but has not bounced back strongly in the OECD as a whole, even as economic growth returned. This trend reflects an ongoing shift to services, consumers responding to high energy prices and improvements in energy efficiency. In OECD countries, power demand will be lower in 2040 than in 2014.
• The penetration of renewables will double to 46% of world electricity output by 2040 with variable renewable technologies such as wind and solar accounting for 30% of generation – up from 5% in 2014. As this penetration rises, countries will need to add flexible capacity that can help meet peak demand, as well as ramp up when solar comes off-line in the evening.
• Daily load profiles are also getting ‘peakier’, reflecting more household and commercial consumption and less steady industrial baseload. As this trend increases over time, power systems will need to increasingly reward system services such as demand response, battery storage, interconnectors and control systems that work along with traditional firm capacity to help match supply with demand.
• Despite significant growth in renewables, fossil fuels will maintain a 44% share of generation in 2040 – albeit down from two-thirds in 2014. Some 1,291GW of new coal-fired capacity will be added to 2040, and 99% of this will be in developing countries where supply is relatively cheap and climate change policies weak or yet to be implemented. Only 1,359GW of gas will be added globally – 86% in developing countries – as its role as a 'transitional fuel' looks more and more doubtful outside the US where the shale gas revolution and environmental regulations seem set to push coal out of the market.
• CO2 emissions from the power sector will rise by 13% over 2014-40. The utilisation of lowcost domestic fossil-fuel reserves from developing countries, the long life of coal plants and the absence of a strict regulatory framework will mean power sector carbon emissions are likely to peak around 2029 at 15.3Gt, then ease only slowly to reach 14.8Gt in 2040.
• More than half of the new generating capacity to 2040 will be built in Asia Pacific so that for every 1GW of new build in the Americas, 3.4GW will be installed in APAC. China alone will attract $3.3 trillion of new investment – nearly double the total for the Americas – and build 2,601GW more capacity by 2040.
• In Europe, small-scale solar will increase its share of the capacity mix to 22% from 6% in 2014 as households and businesses try to offset high retail power tariffs. Meanwhile environmental legislation, the age of the coal fleet, the EU carbon price and the technology’s relative inflexibility will nearly halve coal capacity. By 2040, just under 50% of generation will come from variable sources like wind and solar.
• In the Americas, the US story to 2020 will be all about gas, which will see 90% of new build, thanks to low wholesale prices and coal retirements. From 2020 however it is small-scale solar that dominates, with 21GW added per year. At the same time, Latin America will invest just under $500bn in wind and solar as it tries to diversify away from an over-reliance on drought-prone hydro over the next 25 years.
• In the Middle East & Africa, some 38% of new capacity will be fossil-fuelled as countries seek to exploit their substantial reserves. But we also expect 160GW of solar PV as many of these nations exploit their world-class solar potential. Despite the prevalence of subsidised retail power tariffs, as much as 40% of the new solar could be small-scale systems, used for example to build mini-grids to electrify communities sited away from the main grid.
