Solar power has broken new records in the UK by providing nearly a quarter of the country’s electricity needs, thanks to sunny skies and relatively low summer demand.

National Grid said the thousands of photovoltaic panels on rooftops and in fields across the UK were generating 8.7GW, or 24.3% of demand at 1pm on Friday, smashing the previous high of 8.48GW earlier this month.

Experts said the unprecedented share for solar energy meant about 60% of the UK’s power was low carbon, taking into account Britain’s wind farms and nuclear power stations too. That figure is normally around 50%.

National Grid, which is tasked with ensuring a match between supply and demand for electricity, said it was excited but unfazed by the challenge of accommodating “significant volumes” of renewables.

Duncan Burt, who manages day-to-day operation of the grid, said: “We have planned for these changes to the energy landscape and have the tools available to ensure we can balance supply and demand.”

Hannah Martin, head of energy at Greenpeace, said: “Today’s new record is a reminder of what the UK could achieve if our government reversed its cuts to support for solar, and backed the clean technologies that could provide jobs, business opportunities and plentiful clean energy for decades to come.”

The milestone reached on Friday is the latest in a series of records for solar, which has grown from almost nothing seven years ago to 12GW of capacity today. Last summer it provided more power than the UK’s last 10 coal-fired power stations.

In April this year, Britain achieved its first-ever full working day without coal powersince it started burning the fuel in 1882, thanks in part to solar energy.

Solar’s rapid growth is overturning conventions for the managers of the UK’s power grid. In March, for the first time ever, the amount of electricity demanded by homes and businesses in the afternoon was lower than it was in the night, thanks to the cut in demand due to solar panels.

Alastair Buckley, a solar expert at the University of Sheffield, said of the latest record: “I think it’s a positive sign. It’s free electricity today, for the consumer, and we should make the most of it.”

He said that with solar continuing to be installed despite the government’s drastic subsidy cuts in 2016, further records will certainly be broken this summer and for years to come.

Buckley said the grid could handle a far greater proportion of solar power than currently seen, because gas power stations could be ramped down. For National Grid, periods of high pressure bringing lovely weather to the UK like this week were: “really predictable, so easy to plan for,” Buckley said.

Robert Gross of Imperial College said: “This doesn’t pose fundamental problem for the grid – many sunnier countries manage a similar proportion of solar on a much more regular basis.”

Government statistics published on Thursday show that UK solar power capacity has grown from 11.3GW in April last year to 12.1GW this year, enough to power 3.8m homes.

A warning has been issued to governments across the Caribbean, including Jamaica, to do more to make countries resilient to climate change as there is a price to pay if nothing is done.

According to a report commissioned by the Commonwealth Marine Economies Programme, the Caribbean is “in the front line” and at greater risk from more severe impacts than many other parts of the world because of its geographic location as most regional states are smaller islands where people live close to and depend on the sea.

The Caribbean Marine Climate Change Report Card 2017, which was conducted by scientists and researchers, said more intense storms, floods, droughts, rising sea levels, higher temperatures, and ocean acidification are major threats to all regional economies and pose a danger to lives as well, both directly and indirectly.

“As the seas, reefs and coasts on which all Caribbean people depend are under threat, much more needs to be done to protect these resources, and the authors recommend building more resilient environments to prepare for, and protect against, climate change,” the report noted.

It has recommended developing a regional network of marine protected areas designed to future-proof marine biodiversity against climate change and stabilise shorelines to preserve natural barriers such as mangroves, salt marshes, and coral reefs.

STRONG HURRICANES TO INCREASE

The scientists warn that while the overall frequency of Atlantic storms may decrease, the strongest hurricanes are likely to increase. Global average sea level is projected to rise by a further 10-32 inches over the coming century a devastating amount for a country as low-lying as Cayman, where it could be even worse.

“In the northern Caribbean, sea-level rise could be 25 per cent higher than the global average due to other physical factors affecting land elevation,” the report states. “This projected rise in sea level and severe storms is likely to increase the risk of storm-surge events for Caribbean states, which will further exacerbate risks to biodiversity, settlements and infrastructure.”

The report also zeroed in on some countries in the region including Jamaica, Belize, St Vincent and the Grenadines, Guyana and St Lucia.

Where fishing is concerned, the researchers noted that if there is no action – permanent fishing camps on low lying offshore cays may be completely submerged by future sea level rise, and these are particularly vulnerable during extreme-weather events.

Kelly Tomblin, who has been the face of the Jamaica Public Service Company (JPS) since she joined the light and power company as president and chief executive officer in 2012, is on her way out of the company, and heading to take up the CEO position at the United States-based power company, INTREN, effective July 10.

Tomblin will take over the day-to-day running of the firm from Loretta Rosenmayer, the firm’s founder and current CEO, who will now chair the board of what has become one of the leading utility contractors in North America.

Up to press time, Tomblin was off the island and unavailable for a comment. However, 4-traders.com, a reputable international stock market and financial news website, said Tomblin had confirmed to them that she is to be the new CEO at INTREN.

“INTREN would not be what it is today without Loretta’s vision, leadership and unwavering commitment to high standards and values,” Tomblin was quoted by the website as saying. “I am honoured to lead the INTREN team and continue the progress evolving before me.”

According to reports, Tomblin was selected from a competitive selection process from a strong field of candidates.

“She is a highly impressive and respected executive known for her ability to build diverse, meaningful cultures in a collaborative leadership style. As a recipient of the prestigious 2016 Platt’s Global Energy CEO of the Year Award, Kelly topped an impressive list of finalists leading companies in the United States and around the world,” the website stated.

ENERGY SAVING PROJECTS

During her time at JPS, Tomblin introduced several energy saving projects, as well as the use of liquefied natural gas in the country’s energy mix, even as she guided the light and power company through a profound transformation.

“This evolution comes at an extraordinary time for INTREN,” a report quoted Rosenmayer as saying. “Our momentum is strong, and our management team and employees have built an exceptional company that is one of the most trusted and respected in the industry. I’m confident Kelly is ideally positioned for her new role to continue our growth.”

INTREN has been an innovative solution partner, dedicated to building and maintaining the infrastructure of the energy industry for more than 25 years, and has served many of the nation’s foremost utility companies, private contractors and developers, and municipalities and cooperatives.

The Tesla solar roof is a wonderful innovative technology that will revolutionize the solar industry especially as more companies start to produce their own solar roofs. Tesla launched their solar roof with combined Powerwall battery system this week and everyone got very excited. But how excited should we be in Jamaica?

Here at Solar Buzz we get a lot of calls regarding new technology and the solar roof has been on people’s minds for 7 months since the initial announcement. My response to prospective solar clients would be to not get too excited about owning a solar roof in Jamaica anytime soon, for a few reasons:

  • Not available outside USA initially: If you go to the Tesla Solar Roof page there is a calculator. It will predict the cost of the roof but this calculator only works for US addresses. As with the Tesla Powerwall battery system, which launched over 2 years ago, demand will be high and availability will be limited to the USA until all the kinks are worked out. I have yet to come across a Tesla Powerwall battery system in Jamaica so I would not look for a solar roof in Jamaica for a while.
  • New technology is expensive: The solar roof is very new therefore the price is going to be very high. On the Tesla calculator I typed in a Florida address and put the house size at 2,000sf, the costing is below:

Screen Shot 2017-05-12 at 7.26.48 AM

A 2,000sf roof would cost J$10,500,000 before shipping and is estimated to offset 70% of your electricity bill. Florida has a solar tax credit but Jamaica has much higher energy costs so let’s say these even out for simplicity. A rough payback of this roof in Jamaica would be about 20yrs which puts us back to the early days of solar when regular panels were expensive at US$2/watt compared to US$0.50/watt now. Solar did not sell in those early days because the payback was too long. Actually solar is very cheap now and the solar market still struggles in Jamaica! This is mostly due to the lack of and a tedious financing process in Jamaica but that’s a whole different thesis.

  • The Tesla calculator assumes the home would only need one Powerwall battery bank which produces 14kWh. For a home with a family of four, the solar system would mostly likely need at least two Powerwall battery banks to achieve 100% offset, so add another US$7,000 to the cost.

This assessment is not to discourage anyone towards the solar roof as eventually all roofs will be made of solar tiles. However until that time conventional solar systems are at their most inexpensive levels of all time. A homeowner could buy a new roof and install a traditional solar system to offset 100% of electricity costs and payback for both in half the time of a Tesla solar roof right now. Eventually this will change but at this moment in time do not bank on a solar roof being available in Jamaica or feasible for many years to come. The time you spend waiting  on the Tesla solar roof in Jamaica you could have bought a traditional solar system, a new roof and paid off both through your energy savings.

Solar Buzz Jamaica CEO-Jason Robinson

Tesla Motors CEO Elon Musk.

Electric car maker Tesla has added another product to its line-up: Solar roof tiles.

As of Wednesday, customers worldwide could order a solar roof on Tesla’s website. Installations will begin next month in the United States, starting with California. Installations outside the US will begin next year, the company said.

The glass tiles were unveiled by Tesla last fall just before the company merged with solar panel maker SolarCity Corp. They’re designed to look like a traditional roof, with options that replicate slate or terracotta tiles. The solar tiles contain photovoltaic cells that are invisible from the street.

Tesla CEO Elon Musk said one of the drawbacks to home solar installations has been the solar panels themselves: They’re often awkward, shiny and ugly. Buyers will want Tesla’s roof, he said, because it looks as good or better than a normal roof.

“When you have this installed on your house, you’ll have the best roof in the neighbourhood. The aesthetics are that good,” Musk said in a conference call with media.

The roof is guaranteed for the life of the home, which is longer than the 20-year lifespan for a typical, non-solar roof, Musk said. It has gone through the same hail, fire and wind testing that normal roofs endure.

Tesla’s website includes a calculator where potential buyers can estimate the cost of a solar roof based on the size of their home, the amount of sunlight their neighbourhood receives and federal tax credits. They can also put down a refundable US$1,000 deposit to reserve a place in line.

Tesla said the solar tiles cost US$42 per square foot to install, making them far more costly than slate, which costs around US$17 per square foot, or asphalt, which costs around US$5. But homes would only need between 30 and 40 per cent of their roof tiles to be solar; the rest would be Tesla’s cheaper non-solar tiles which would blend in with the solar ones.

Save On Installation

It would cost US$69,100 to install a solar roof with 40-percent solar tiles on a 2,600-square-foot roof in suburban Detroit, according to Tesla’s website. That includes a US$7,000 Tesla Powerwall, a battery unit that stores the energy from the solar panels and powers the home. The roof would be eligible for a US$15,500 federal tax credit and would generate an estimated US$62,100 in electricity over 30 years. Over that time period, Tesla estimates, the homeowner would save US$8,500.

Tesla said the typical homeowner can expect to pay US$21.85 per square foot for a Tesla solar roof. The cost can be rolled into the homeowner’s mortgage payments and paid for over time, the company said.

Musk wouldn’t say how many orders the company expects to get this year. He expects the initial ramp-up to be slow.

“It will be very difficult and it will take a long time, and there will be some stumbles along the way. But it’s the only sensible vision of the future,” Musk said.

Palo Alto, California-based Tesla Inc is making the solar tiles at its Fremont, California, factory initially. But eventually all production will move to a joint Tesla and Panasonic Corp factory in Buffalo, New York. Panasonic makes the photo-voltaic cells used in the solar tiles.

Tesla said it will be installing equipment in the Buffalo factory over the next few months.

Dr Orville Grey (right) in action at the international negotiating table

JAMAICA CONTINUES to occupy positions of influence in the global architecture designed to work in the interest of climate change security for all, and in particular developing countries.

Just over a month ago, Dr Orville Grey, senior technical officer responsible for adaptation in the Climate Change Division, was elected co-chair of the Executive Committee (Excom) of the Warsaw International Mechanism for Loss and Damage (WIM).

He, along with Monika Antosik of Poland, was elected at the fifth meeting of the Excom, held in Bonn, Germany, between March 21 and 24.

The WIM was established at the 19th meeting of the parties to the United Nations Framework Convention on Climate Change (UNFCCC), held in Warsaw in 2013.

Its mandate is “to address loss and damage associated with impacts of climate change, including extreme events and slow onset events, in developing countries that are particularly vulnerable to the adverse effects of climate change”, according to the UNFCCC website.

Its specific functions include:

– Enhancing knowledge and understanding of comprehensive risk management approaches to address loss and damage associated with the adverse effects of climate change, including slow onset impacts;

– Strengthening dialogue, coordination, coherence and synergies among relevant stakeholders; and

– Enhancing action and support, including finance, technology and capacity building, to address loss and damage associated with the adverse effects of climate change.

Clifford Mahlung, a meteorologist and seasoned climate change negotiator, representing small-island developing states, has been appointed co-chair of the Adaptation Committee.

The Adaptation Committee was established in 2010, as part of the Cancun Adaptation Framework “to promote the implementation of enhanced action on adaptation in a coherent manner under the Convention”.

Its functions include:

– Providing technical support and guidance to the parties to the UNFCCC and sharing relevant information, knowledge, experience and good practices;

– Promoting synergy and strengthening engagement with national, regional and international organisations, centres and networks; and

– Considering information communicated by parties on their monitoring and review of adaptation actions, support provided and received.

“Jamaica is doing its part to ensure that the bodies of the convention and now the Paris Agreement will work to the full benefit of the parties and that we have our interest being represented at the highest level,” Mahlung told The Gleaner.

Added Grey: “It continues to show Jamaica as a leader on important issues. In this context, it is something related to climate change and provides us with an opportunity to shape what is happening in that debate and gives first-hand options to include something from loss and damage into our own national policies.”

Neither would take any personal credit for their appointments.

“It shows the confidence that has been placed in me by my developing country colleagues, in particular the members of the SIDS, who I represent, and the developing countries on the whole who appointed me to be elected as their co-chair,” said Mahlung, whose appointment also became effective in March.

Grey indicated that his new role is indicative of “the confidence of SIDS in championing the case of something that is critical to our future, which is the impact of loss and damage associated with the impacts of climate change”.
