An all-electric taxi, releasing no emissions into the local environment

The 100% electric Dynamo taxi manufactured in Coventry has been created by Dynamo Motor Company – a division of ADV Manufacturing – in conjunction with Nissan. It was launched at the Private Hire & Taxi Exhibition at the MK Arena in Milton Keynes.

The vehicle, which the firm had spent several years developing, has been designed for use in towns and cities aiming to reduce their emissions levels. It will comply with Transport for London’s stringent operating requirements as well as new zero emission legislation coming into force in January 2018.

The five-seat Dynamo taxi, with full side wheelchair access, will have a range of 100 miles and can be re-charged in 30 minutes when using a Rapid Charge Post. As more of these are being installed throughout the country, its major cities and towns will be connected by charging hubs and drivers of electric vehicles will no longer need to make detailed plans for longer journeys.

Brendan O’Toole, chairman at Dynamo said “We’re at the start of the biggest change in the motoring world since the era of Henry Ford because most of us will be driving electric vehicles in the future. This is a pioneering new chapter in motoring and, if anything, driver selection of electric cars will continue to accelerate since they provide zero emissions for the environment which is important as we all continue to learn more about the damage to our health from pollution.”

The company plans to start selling the regional Dynamo taxi vehicle in the summer and is hoping the London version will be on sale in the autumn.

Ed: though electric vehicles emit no emissions into the local environment we must look forward to a day when they run on electricity generated by solar, wind, hydro and tidal installations. Coal and oil power stations release sulphur dioxide gas, which causes breathing problems and contributes to acid rain and carbon dioxide, which adds to the greenhouse effect and increases global warming. 

Germany’s people-powered energy and American micro-grids

A 2015 National Geographic article with the most remarkable photographs: Germany Could Be a Model for How We’ll Get Power in the Future … led to the ISLR article written earlier this month.

The Institute for Local Self-Reliance (ISLR) informs readers that its mission is to provide innovative strategies, working models and timely information to support environmentally sound and equitable community development. To this end, ILSR works with citizens, activists, policymakers and entrepreneurs to design systems, policies and enterprises that meet local or regional needs; to maximize human, material, natural and financial resources; and to ensure that the benefits of these systems and resources accrue to all local citizens.

Instead of expanding or connecting to the national energy grid, some companies, municipalities, and individuals are creating miniature grids of their own that can operate independently – “microgrids” – providing options for groups that want lower energy bills, more control over where their energy comes from, or a level of reliability that the grid cannot provide.

The costs are high and they are economically viable for only a limited set of situations. As Karlee Weinmann, ISLR Energy Democracy Initiative Research Associate pointed out, however, the cost of new technology invariably falls as it is adopted: “The cost of materials, installation, and maintenance for the components that make up a microgrid are going down, so the value proposition for a microgrid increases in turn. The general viability of microgrid projects is also reinforced through replication, like anything else, so the more that various stakeholders test the technology, prove its value, and improve upon it, the easier it is to justify buying in . . . As we see it, the future of the grid will be far more decentralized than the system we have now. Rather than paying a far off utility for electricity, which in many cases comes from problematic, dirty sources, customers’ money can stay closer to home.”

Hurricane Sandy, which cut power to 8.5 million people, one million of whom went without power for a week, was cited by the ILSR report Mighty Microgrids as one of the key motivators of regional investment in microgrids. While up to 60% of backup diesel generators failed in medical centers and other essential facilities, Princeton University’s 20 MW microgrid kept the campus operational in island mode for three days while a connection to the grid was being restored.…

Regulations governing interconnection processes can also hinder microgrid adoption, particularly because these regulations vary from state to state. Opposition from utility companies is often a factor that makes the regulatory environment hostile or resistant to positive change. In an ideal world, a national standard would be adopted.

Richardson concludes: “Perhaps in the future, microgrids will be a common feature of communities . . . connected by the larger grid and selling electricity to each other as necessary. For now, they represent a useful tool for businesses and communities that need reliability that the grid can’t offer or that can leverage scale to reduce energy costs”.

 

 

 

Antidotes were hard to find this week as one cheering message after another was debunked – only Positive News was buoyant

The message in so many headlines: “From January 1st this year, all Dutch electric trains are being powered by renewable energy – wind power. Not so, it is claimed: 100% wind power because it has a contract with various wind farms to produce enough energy to power its rail system, but this is just an accounting transaction. Only a small fraction of the power delivered to its trains actually comes from wind. 

global-fossil-fuel-subsidies-graphThen Jonathan Ford in the FT (former chairman of the Cameron generation of the Bullingdon Club, now responsible for writing and commissioning the FT’s editorials) argued that green jobs are not valuable because of public subsidy (How subsidy culture keeps Britain’s green industry in the black – leaving the uniformed or prejudiced reader to assume that fossil fuels receive no subsidy. Statistics for the UK are not readily available here – but the IMF reports that America is the world’s second biggest culprit overall, spending $669 billion this year—mostly by “post-tax” systems which fail to factor the costs of environmental damage into prices.

Leonie Greene, Head of External Affairs, Solar Trade Association replied in the FT that the UK subsidy is required only because the “polluter pays” principle has not been fully applied to fossil fuels.

She adds that despite the global market failure to tax carbon pollution, there are increasing parts of the world where solar and onshore wind compete with the cheapest fossil fuels even without subsidy or “polluter pays” taxes.

Cheaper batteries for domestic solar energy and grid-scale storage

As disturbing news piles up, so does news of the sort of positive developments covered on this site. Today’s post was going to be about the news that “as of the first of January this year, all public transport trains in the Netherlands are being powered by renewable energy” (wind) first brought to me by Futurism.

elon-muskThat subject is being set aside as it has been very widely covered in the MSM. So instead we turn to specific news about the work of Elon Musk (left), a co-founder of PayPal who is now chairman of Tesla Motors.

The FT reports that householders are starting to buy more battery storage systems as costs come down and consumer interest is rising in Tesla, the electric car company founded by Elon Musk, which is also making the Powerwall domestic battery.

“Tesla’s market entry has led to a surge of interest from the media and public alike in a way that rarely happens in the energy sector,” the UK Renewable Energy Association said in a report published earlier this week.

In February last year the Guardian reported that Mark Kerr became the first British owner of a Tesla Powerwall. Kerr and his family tend to be out at work and school when the sun is shining and the 16 solar panels on the roof of their home in Cardiff are producing power. The excess is fed into the grid and they make a return on it but they are not able to use the power from their panels.

However, from now on, energy produced but not used during the day will charge the Powerwall and provide them with the energy they need when they’re at home and their lights, music centres, computers, televisions and myriad other devices need feeding.

Jonathon Porritt – who recently wrote about the relatively low prices of solar tiles produced by Musk – gives a ‘wee glimpse’ into the transformative impact of cheaper storage technologies, on this video of a presentation by Tony Seba which focusses on their use in cars..

While cheaper battery storage offers potential benefits to renewable power stations and homeowners, industry analysts said that grid-scale storage could also produce large savings by reducing the need for new power stations and transmission lines.

WEF: installing new solar panels is now cheaper than comparable investment in coal, natural gas, biomass or fracking

michael-corenThe bearer of this week’s good tidings is Yale graduate Michael J. Coren (left) of Quartz, which is designed by its experienced founders to deliver information primarily to users of tablet and mobile then to website readers.

To summarise: the World Economic Forum (WEF) reported in December that the renewable energy future has arrived – solar and wind is now the same price or cheaper than new fossil fuel capacity in more than 30 countries.

Coren reports that Michael Drexler, who leads infrastructure and development investing at the WEF, issued a statement adding that renewable energy is not only a commercially viable option, but a compelling investment opportunity with long-term, stable, inflation-protected returs.

wef-re-coverIn 2016, utilities added 9.5 gigawatts (GW) of photovoltaic capacity to the US grid, making solar the top fuel source for the first time in a calendar year, according to the US Energy Information Administration’s estimates. The US added about 125 solar panels every minute in 2016, about double the pace last year, reports the Solar Energy Industry Association.

But global investment in renewable energy still lags behind levels needed to avoid potentially catastrophic global warming, according to the United Nations. Global renewable investment last year was $286 billion, or 25% of the $1 trillion goal set by nations at the Paris climate change accord.

As prices for solar and wind power continue to fall, two-thirds of all nations will reach the point known as “grid parity” within a few years, without subsidies. Renewable energy technology, especially solar and wind, has made great gains in efficiency in recent years with advances in manufacturing processes and economies of scale considerably reducing production costs

Solar photovoltaic systems have seen a reduction of up to 22% for every doubling in production capacity and price compression of 80% since 2009, according to the International Renewable Energy Agency (IRENA) citing EPIA, 2011a and Kersten 2011. Its working paper is part of a set of five reports on solar photovoltaics, wind, biomass, hydropower and concentrating solar power that address the current costs of these key renewable power technology options. Wind turbine prices have fallen by more than 30% over the past three years. Solar is projected to fall to half the price of electricity from coal or natural gas within a decade or two. That milestone has already been reached in some places. In August, energy firm Solarpack contracted to sell solar electricity in Chile at just $29.1 per megawatt hour, 58% below prices from a new natural gas plant.

grid-parity2-2015See clearer version here: https://www.db.com/cr/en/concrete-deutsche-bank-report-solar-grid-parity-in-a-low-oil-price-era.htm

It is estimated that more than 30 countries have already reached grid parity without subsidies, and around two thirds of the world should reach grid parity in the next couple of years. If electricity costs were to rise by 3% annually, 80% of the global market would reach grid parity in the next couple of years, according to Deutsche Bank. A search produced the Deutsche Bank 2015 report: Solar grid parity in a low oil price era and the map above. Countries that have already reached grid parity include those in which demand is rising at a fast pace (e.g. Chile, Mexico) or insolation is high (e.g. Brazil, Australia).

Dolf Gielen, Director, Innovation and Technology, stresses in the preface to the Irena report that though in recent years there have been dramatic reductions in renewable energy technologies’ costs as a result of R&D and accelerated deployment policy-makers are often not aware of the latest cost data.

Many will share his hope that presenting this data will inform the current debate about renewable power generation and assist governments and key decision makers to make informed decisions on policy and investment.

 

 

 

Costa Rica celebrates 113 days of 100% renewable energy

cr-header

As three of the world’s biggest insurers called on G20 leaders to implement a timeframe for the end of fossil fuel subsidies when they met in China, Costa Rica led the way.

In 2009, President Arias declared a goal of making Costa Rica the world’s first carbon neutral country, reducing net global warming emissions to zero.

With a 113-day stretch of 100-percent renewable energy under its belt and several months left in the year, Costa Rica is edging closer to its target. Costa Rica could be on track to match the record set with its renewable energy production last year, which accounted for 99 percent of the country’s electricity. That included 285 days powered completely by renewable sources, according to the Costa Rican Electricity Institute. Related: Costa Rica achieved 99-percent renewable energy use in 2015

Costa Rica is able to take advantage of a multitude of renewable energy sources because of its unique climate and terrain. Most of the nation’s renewable energy comes from hydropower, due to its large river system and heavy tropical rainfalls. Solar, wind, biomass, and geothermal energy also play key roles.

The tropical nation aims to be free from fossil fuels in just five years. With hefty investments in geothermal energy projects and a forecast for more heavy rains in the coming years, that goal could be accomplished even sooner than originally planned.

In 2015 Costa Rica achieved 99% renewable energy

Costa Rica’s lush jungles and waterfalls make hydropower one of the most accessible natural energy resources in the country, yet geothermal plants are catching up quickly, and officials hope to continue to build this and other industries. A statement from earlier this month boasted 100% renewable energy use for 285 days this year. Albeit a truly impressive achievement, the country’s goal is still 100 percent independence from fossil fuels all year.

Wind, biomass, and solar power are also viable alternative energy sources. With the focus shifting toward addressing fossil fuel used in the transportation sector, the country hopes to hit its goal of being carbon-neutral by 2021. Costa Rican citizens seem to be behind the measures, especially as they have seen energy costs drop 12% over the last year, with future projections dropping even more.

 

 

Innovation, resilience and co-operation in war-torn Syria

In 2010 it was reported that the Syrian Ministry of Higher Education had launched programmes on renewable energy to be studied at the faculties of electrical, mechanic and technical engineering and in the institutes and postgraduate programs. Research and training energy centers had been established in Damascus, Aleppo, Tishreen and al-Baath universities.

However the progress of these programmes have been adversely affected by four years of air strikes, street battles and sieges.

Now, though the widespread infrastructure damage in the areas around the capital Damascus means that thousands of Syrians have no more than a few hours of power a day, a resourceful, resilient spirit is enabling many survivors to cope with only a few hours of power a day by modifying their way of life and innovating.

Almost all Syrians have switched to using longer lasting LED lights which are cheaper than candles and can be powered with a car battery. In the war affected areas, people go to bed early and most now wash their clothes by hand, having sold machines and refrigerators.

Some are also finding ways to make their own power, using solar panels, fuel made from plastic bags and even bicycle-powered batteries. 

syrian solar panelsIn southern Syria, many shops sell solar power panels for $20-$200 and some are used in shelters at a refugee camp in Aleppo. Omar al-Golani, a media activist in the town of Kwdana, said that even the poorest will try to borrow money to buy them, or sell their food rations. In May, Rami al-Sayyed told the Financial Times that he and many of his neighbours started generating electricity by pedalling bicycles about three years ago. He would pedal his bike for two hours every day to charge his laptop.

A few Syrians are also using wind energy, reports Khaled Issa, from Idlib. They buy fans, or make their own, and place them on the roof.

Most Syrians save fuel for farming equipment, generators that power shops and hospitals, or machines used to dig victims out of bomb sites. Since late 2013, in the besieged suburbs around Damascus, people have collected and burnt plastic bags and the cooled liquid plastic produced can be made into a substitute for diesel or kerosene.

Rami al-Sayyed points out that the shortages have brought about moments of community spirit. Some of his neighbours came together to put up a bicycle and take turns to pedal in order to watch new TV programmes released during Ramadan.
