Small-scale solar power is changing lives and disrupting traditional models

Published

on

Solar power is becoming an increasingly important part of the planet’s energy mix. In 2016, solar photovoltaic grew faster than any other fuel, with China responsible for nearly half of worldwide expansion, according to the International Energy Agency (IEA).

While solar power projects can be grand in scale there are some that, while smaller, are no less important. Repowering London, a not-for-profit based in the U.K. capital, helps facilitate community-owned renewable energy projects there.

In October 2015, Banister House in Hackney, east London, became home to the borough’s first community-owned solar power project. The project was developed by Repowering London, residents of Banister House and Hackney Energy.

Banister House Solar, as the scheme is known, produces community-owned renewable electricity for the building and its residents. According to Repowering London, 679 tons of carbon dioxide will be prevented from entering the atmosphere during the project’s 20-year lifetime.

A small community generating its own energy is not restricted to large urban conurbations. In Scotland, for example, the Findhorn Ecovillage is home to four community-owned wind turbines with a total capacity of 750 kilowatts.

These turbines help make the village a net exporter of electricity. According to those behind the project, around half of the electricity generated is used on-site through a private grid, with the rest sent to the main grid.

Back in the capital, Agamemnon Otero, CEO of Repowering London, said that smart meters had also been installed for residents so that they can see what they are generating. The cost of the project, around £150,000 ($209,148), was raised by members of the public, with investors getting a share of the profit when energy is sold back to the grid.

“While it might not seem a large amount, £150,000… all of it was raised from the local community within eight weeks,” Otero said.

“There’s a 4 percent return on their investment, there (are)… savings to the building owner so that the actual council is making savings as well. The financial benefits stream out both for members and the partners involved.”

The G-7 heads to Cornwall, home of the Eden Project

Published

on

This June, leaders from countries including the U.S., U.K., Germany and Japan will congregate in Cornwall, a picturesque county in the southwest of England, to take part in the G-7 summit.

The small coastal resort of Carbis Bay will be the epicenter of the talks, with larger towns including St Ives and Falmouth set to play a supporting role.

While Cornwall is rightly famed for its natural beauty, fishing communities and pristine beaches, it’s also home to one of the most interesting developments in Britain: the Eden Project.

A popular tourist attraction located near the town of St Austell — around an hour’s drive from Carbis Bay — the Eden Project was officially opened in 2001.

The site is instantly recognizable thanks to its “Biomes,” which are bubble-like structures housing vast indoor gardens packed with plants from across the world.

Below, CNBC looks at some of the other design features and technologies which have helped the Eden Project stand out from the crowd and attract millions of visitors over the years.

Monitoring tech

In a bid to cut its energy consumption, the Eden Project — which is temporarily closed to visitors because of the coronavirus pandemic — makes use of a building management system, or BMS.

Its official site describes this as resembling “a giant TV remote” which enables “very tight control of our heating and electrical systems.”

The BMS monitors usage within the Biomes, offices and other buildings at the complex and ensures the site never uses more than it needs.

Energy efficiency and insulation

In addition to the BMS, a range of on-the-ground technologies are being deployed to boost the energy efficiency of the Eden Project.

These include the installation of LED lighting and use of high-efficiency boilers.

Buildings at the site have also been designed to make the most of natural light and ventilation, while an emphasis has also been placed on the use of “super insulation.”

Hexagonal cushions on the Biomes’ steel structure are used to capture air between two layers of a material called ethylene tetrafluoroethylene, creating a “thermal blanket.”

Elsewhere, insulation comes in the form of recycled newspapers, while a green roof located on a building used by staff attracts wildlife and helps keep things cool during the summer and warm in winter months.

Renewables

While the site has placed a great deal of focus on energy efficiency, it’s also embracing renewable energy technologies.

A 30 kilowatt (kW) solar power system has been installed on the rooftop of the Eden Project’s Core building — which is used for education purposes — while a 5 kW wind turbine is located near the site’s car park.

These technologies are supplemented by a deal with Good Energy, which supplies the Eden Project with 100% renewable energy.

5G connectivity

Just last week, it was announced a consortium headed up by the Eden Project was one of nine picked to take part in the Department for Digital, Culture, Media and Sport’s “5G Testbeds and Trials Programme.”

Called Eden Universe, the Eden Project consortium will benefit from a grant of £1.6 million ($2.18 million), with a 5G network and 360-degree video technology set to be installed on-site.

Among other things, the tech will allow teams at the Eden Project to create and test a range of augmented and virtual reality programs and “experiences” for visitors.

Sustainable transport

In addition to the tech which has been integrated into the fabric of the Eden Project’s buildings, efforts are also being made to encourage the use of sustainable transport.

To this end, discounts are available for visitors who cycle, walk or use combined coach, bus and train tickets.

Staff at the Eden Project can also make use of an 18-strong fleet of zero-emission electric vehicles from French carmaker Renault.

IEA cuts 2021 demand outlook on renewed Covid lockdown measures

LONDON — The International Energy Agency on Tuesday cut its 2021 global oil demand forecast, citing soaring Covid-19 cases and renewed lockdown measures that will further limit mobility.

The IEA said it now expects world oil demand to recover by 5.5 million barrels per day to 96.6 million this year. That reflects a downward revision of 0.3 million barrels from last month’s assessment and follows an unprecedented collapse of 8.8 million barrels per day last year as the coronavirus pandemic battered global oil markets.

The IEA’s latest oil market report comes as countries continue to implement strict public health measures in an attempt to curb virus spread, with lockdowns imposed in Europe and parts of China.

The Paris-based energy agency said oil demand growth was projected to fall slightly during the first three months of the year in the wake of tougher government plans that call for additional travel restrictions.

This is expected to curb worldwide mobility once again, prompting the IEA to trim its first-quarter forecast for oil demand growth to 94.1 million barrels per day. That would see oil demand return to near year-ago levels and reflects a downward revision of 0.6 million barrels from December’s oil market report.

“The global vaccine roll-out is putting fundamentals on a stronger trajectory for the year, with both supply and demand shifting back into growth mode following 2020’s unprecedented collapse,” the IEA said in its closely-watched report.

“But it will take more time for oil demand to recover fully as renewed lockdowns in a number of countries weigh on fuel sales,” it added.

Oil prices

Oil prices have rallied in recent weeks, supported by optimism over Covid vaccine rollouts and a surprise oil production cut from OPEC kingpin Saudi Arabia.

However, the relatively slow pace of inoculations has raised doubts over how soon economies can recover.

International benchmark Brent crude futures traded at $55.26 a barrel on Tuesday morning, up more than 0.9%, while U.S. West Texas Intermediate futures stood at $52.51, around 0.3% higher.

Both benchmarks fell more than 2.2% in the previous session, notching their worst daily performance since Dec. 21.

OPEC and its non-OPEC allies, an alliance sometimes referred to as OPEC+, cut oil production by a record amount in 2020 in an effort to support crude prices, as strict public health measures worldwide coincided with a fuel demand shock.

OPEC+ initially agreed to cut output by 9.7 million barrels per day, before easing cuts to 7.7 million and eventually scaling back further to 7.2 million from January. OPEC’s de facto leader Saudi Arabia has since said it plans to cut output by an extra 1 million barrels per day in February and March to stop inventories from building up.

Last week, OPEC kept its 2021 forecast for worldwide oil demand unchanged. The 13-member group anticipated demand growth to increase by 5.9 million barrels per day year on year to average 95.9 million.
