Britain achieves first ever coal-free day ‘since Industrial Revolution’

226. coal-free day

Energy sources such as gas, wind, solar and nuclear allowed Britain to keep things switched on for 24 hours without the use of coal-fired power plants.

Last Friday (21 April 2017) saw Britain’s energy demand be met without the use of coal power for the first time since the industrial revolution, according to National Grid.

Prior to this, the UK’s longest period without coal power had been 19 hours – achieved both on a weekday and weekend in May 2016.

A spokesman for National Grid said the record period was a demonstration of things to come, with coal-free days becoming more common.

Inrecent years, coal has significantly decreased, accounting for only 9% of electricity generation in 2016, down from 23% in 2015, as coal power plants have closed or shifted to burning biomass such as wood pellets.

Britain was the first country to make use of coal for electricity when Thomas Edison opened the Holborn Viaduct power station in London in 1882.

Now, as part of a government plan, Britain’s last coal power station will be forced to close in 2025, to meet its climate change commitments.

“The first day without coal in Britain since the Industrial Revolution marks a watershed in the energy transition. A decade ago, a day without coal would have been unimaginable, and in 10 years’ time our energy system will have radically transformed again”, says Hannah Martin, head of energy at Greenpeace UK.

She added: “The direction of travel is that both in the UK and globally we are already moving towards a low carbon economy. It is a clear message to any new government that they should prioritise making the UK a world leader in clean, green, technology.”

Head of climate and energy at WWF, Gareth Redmond-King, described Britain’s first coal-free day as “a significant milestone in our march towards the green economic revolution”.

“Getting rid of coal from our energy mix is exciting and hugely important. But it’s not enough to achieve our international commitments to tackle climate change – we haven’t made anything like the same progress on decarbonising buildings and transport. Whoever forms the next government after the general election, they must prioritise a plan for reducing emissions from all sectors.” He added.

Space-based solar power: Powering the earth

Solar Power In Space

Around 1.2 billion people in the world don’t have access to electricity. A further 1 billion don’t have reliable electricity networks needed for powering medical equipment and other basic requirements, according to a United Nations Foundation report.

“Solar power satellites introduce the profound capability to send clean, constant energy nearly anywhere in the world, which would be huge for places that don’t currently have reliable electricity,” says Paul Jaffe, a spacecraft engineer at the U.S. Naval Research Laboratory in Washington, D.C.

Why solar panels in space are a good idea?

Of all the energy sources available on earth, the sun is as good as it gets. However, on earth, solar power is generally reduced by night, cloud cover, atmosphere and seasonality.

Solar panels also take up a lot of land, and around 30% of all incoming solar radiation never makes it to ground level.

“To power the entire world with solar power, we would need to cover an area that’s 92% the size of Nevada in solar panels, and that’s not even counting the batteries,” says Lewis-Weber in his published a paper, New Space.

In space the sun is always shining, there is no weather to compete with and there’s no atmosphere to reduce the intensity of the sun’s rays. In addition, the light that would reach the panels would be 27% brighter, as it would not need to filter through the atmosphere.

How will space-based solar power work?

Self-assembling satellites are launched into space, along with reflectors and a laser transmitter or microwave.

The reflectors or mirrors would spread over a vast area of space, directing light radiation onto solar panels.

The solar panels will then convert the light into either a laser or microwave and send undisturbed power down to earth. Power-receiving stations on earth would collect beams and add it to an electric grid.

space solar power

The Challenges of space-based solar power

Powering the earth would require a LOT of solar panels, and launching all of these up into space is by no means cheap.

A single SpaceX launch costs around $60 million. This means it could cost tens of trillions of dollars to send up a meaningful number of solar power satellites.

Paul Jaffe, who works on space-based solar panels at the U.S. Naval Research Lab, says, “The launch cost is one of the most influential factors in determining the cost of space solar.”

“Without that cost coming down, or using some alternate means to put the spacecraft in place, it’s not going to compete [with fossil fuels] on price”, he added.

In conclusion, space-based solar panels remain a tempting possibility in providing reliable and clean energy to people in in developing countries, or to disaster-stricken areas, without having to rely on the traditional grid to a large local power plant.

The power produced by runners competing in the London Marathon

London, UK- April 13, 2014: London Marathon in Canary Wharf aria, massive sport event for professionals and amateurs sportsmen, Champions League

The London Marathon is considered one of the biggest marathon events in the world, attracting runners of all ages and abilities on one course.

From Blackheath to Greenwich, across Tower Bridge and through the Isle of Dogs, the layout of the marathon route means that spectators can move between different points to cheer on participants.

How much energy does it take to run the London Marathon?

According to Common calculations, the average runner burns around 100 kilocalories per mile.

The London Marathon is a sweaty 26.2 miles, starting near Greenwich Park and ending at St James’ Park.

This totals to 2,620 kilocalories burned throughout the marathon.

With this total, we can then work out how much power is generated by converting this figure into a unit for measuring electricity.

By converting this figure to watts and then kilowatts, 2,620 kilocalories equates to 3.045 kWh.

The power of a single runner

Using the total of 3.045 kWh, a single runner completing the marathon could power:

  • A 40W energy-saving light bulb running for 76 hours straight
  • Charge a smart phone for an entire year
  • The same amount of power a 6kW wind turbine would generate in a windy location

The power of the entire marathon

This year a record total of 253,930 people are expected to participate in the London Marathon.

If a single participant competing in the marathon uses an equivalent 3.045 kWh of energy, then the total amount of energy consumed by the entire marathon would be a mammoth 752.3 mWh.

An average house in the UK uses 4,600 kWh a year in electricity. This means the whole of the London Marathon could exert the equivalent energy needed to power 164 homes for a year.

Timings and what to expect this year:

The event will see Jemima Sumgong defend her title in the elite women’s race, while Kenenisa Bekele is among the star names in a stellar elite men’s field.

The 37th edition of the London Marathon is set to produce more Guinness World Records, and the race promises to be one of the best yet.

The marathon takes place on Sunday 23rd April, 2017, starting at Old Billingsgate at 08:40 – this consists of three-mile races for different youth categories.

The official start times for are as follows:

08:55 – London 2017 World Para Athletics Marathon World Cup in association with the Virgin Money London Marathon elite wheelchair race

09:00 – London 2017 World Para Athletics Marathon World Cup (ambulant athletes)

09:15 – Virgin Money London Marathon for Elite Women

10:00 – Elite Men and the British Athletics and England Athletics Championships for Men and Women and the Virgin Money London Marathon Mass Start

Here’s how other major events such as the Grand National and the Boat Race compare to the London Marathon in terms of power generation.

Grand National vs. The Boat Race: Generating enough energy to power 100,000 TVs

British Gas

British Gas compiled data to highlight the power generated by man and horse during the UK Boat Races and the Grand National.

The UK Boat Races

Watched by thousands this past weekend (Sunday April 2nd) along the banks of The Thames between London’s Putney and Mortlake, and by millions more on TV around the world – The Cancer Research UK Boat Race lived up to its spectator hype.

The Boat Race is an annual rowing race between the Oxford University Boat Club and the Cambridge University Boat Club – this year, it was Oxford who claimed victory.

The Grand National

The Grand National, held annually at Aintree Racecourse in Liverpool, is the most valuable jump race in Europe, with a prize fund of £1 million in 2016.

The handicap steeplechase takes place over 4 miles 514 yards (6.907 km) with horses jumping 30 fences over two laps.

It’s estimated that a quarter of the UK adult population will bet on the Grand National this year, and a TV audience in excess of 10 million is expected to tune in to watch the drama.

0000_Britsh Gas Business_Horses vs. rowers infographic Twitter V2-01

Comparing the power output of man and horse

A racehorse completing the Grand National will use twelve times more energy than an entire Boat Race crew.

British Gas Business research shows that the average male Blue Boat rowing team could generate almost 2.3KWh, the same amount of energy needed to power 200 televisions.

Meanwhile, a 450kg thoroughbred completing the Grand National could use enough energy to power almost 2,500 televisions.

Up to 40 horses compete in the Grand National. If every horse was to cross the finishing line, the total energy used combined with the two Boat Race teams competing could power more than 100,000 televisions across the country for the duration of the respective races.

Could manpower and horsepower generate enough energy for a business to operate?

The average workplace computer uses 0,09 KWh per hour when in use. This means that the average male Blue Boat rowing team could power a workstation for 26 hours.

A racehorse competing in the Grand National will power the workstation for 312 hours.

A compact fluorescent light bulb (CFL) uses 0.014 KWh per hour. A single rowing team competing in the Boat Races could generate enough electricity to run a light bulb for 19 days or 165 hours.

A single racing horse will run the same light bulb for 228 working days or 1980 hours.

The beauty of both manpower and horsepower is that we’re not relying on the erratic nature of the wind or the sun. Of all the renewable fuels, it is unlikely that any is more sustainable than our own bodies.

Self-powering gym workstations are currently one way the human body can help produce electricity.

Technologies such as this will not save the world’s energy crises anytime soon, but they remain a foundation for generating clean energy in the future.


Power on the go: 4 things to consider when buying a power bank

Portable power bank

It’s often frustrating when you’re on the go and your smartphone or tablet dies.

This is where having a portable power bank charger can make a huge difference in keeping your devices fully powered wherever you are. With the increase in their usage for staying connected, there is a need to keep them charged at all times.

Here are 4 key considerations to help you choose the right portable power technology that best suits your travel and power needs.

1. Capacity

If you’re not carrying too many devices when you travel, then you will only require a portable bank with a low capacity to charge your phone. If you’re charging larger devices, such as an iPad or tablet, then you’ll require a higher capacity power bank.

The higher the milliampere hour (mAh), the more capacity the power bank will have. If you have a cell phone with a 1500mAh battery, then a capacity of 1500mAH can fully charge it once. Here is a usage guide:

1500mAh battery: Mobile phone (1 full charge)

5200mAh battery: Mobile phone (2 full charges), Tablet (50% charge)

10000mAh battery: Mobile phone (4 full charges), Tablet (1 full charge)

Higher mAh unit power banks are also available, and there are charges that can power almost all devices, including laptops, iPads, tablets, iPods, action cameras and all mobile phones.

2. Cost vs. Quality

Batteries can explode. Some battery pack makers will tell you on the packaging where the batteries are sourced from.

So, while the cheaper brand-less battery pack sounds like a great deal compared to a branded one, its almost impossible to tell if it cuts any corners with the short circuit, over charging, and temperature protection mechanisms in order to pull off the low price.

3. Portability

Most power banks come with a built-in USB cable, so you don’t have to worry about leaving your devices USB cable at home.

To cater for iOS users, some power banks contain a built-in Lightning cable instead. These often tend to cost more than USB options because they cater for Apple products, where licensing and certification program fees have to be paid.

Higher capacity banks usually come with more than one USB charging port. The biggest advantage of having multiple charging ports is that you can charge more devices at the same time.

If you’re using more than one port, identify the total output current of the battery pack. For example, if you’re using a battery pack with two 2A/5V ports, an output of 2A will be used when only one port is being occupied.

If two ports are connected, the total output may be limited to 3A, with each port getting 1.5A. If a power bank has a total output of 4A, then both devices will be able to charge as fast as they can.

4. Power output

The output of the charger should be equal to the input battery voltage requirement of your device. If it’s lower, you may drain your device’s battery, rather than charging it.

Most power banks will charge mobile phones and mp3 players, but only a selected few can fully recharge your laptop battery.

Larger electronic devices such as this may require a 12V – 24V output rating that is available in larger portable battery packs.

If you’re constantly on the go for business or pleasure, a power bank is definitely worth investing in.


Checklist: 10 ways to save energy in the workplace

Smiling woman making copies in office

Most people don’t know how easy it is to run their businesses on less energy. Here are 10 easy tips to help you save energy and keep your energy bills down.

1. Make use of energy saving features

Most modern day equipment has energy saving features. When replacing old gadgets, make sure to do so with energy efficient peripherals.

Educate your employees with regard to these energy saving features for printers, microwaves, air conditioners, and allow them to use these to cut business energy costs.

2. Use energy-efficient light globes

Compared to traditional incandescent bulbs, compact fluorescent bulbs of the same brightness will save around £3 a year, or £45 over the lifetime of the product, according to the Energy Saving Trust.

Not only do these bulbs last longer, but also use about 75 per cent less energy than standard light bulbs.

3.Allow computers to hibernate

Turning off your workstations when away for long periods of time and shutting down at the end of the day are crucial in saving energy and lowering bills. When in sleep mode, your computer enters a low power state, but while hibernating it uses no power at all.

The hibernation feature on desktop computers and laptops allows you to save your existing work and continue from the same point next day.

4. Switch heaters and coolers off when not in use

Some ducted systems allow you to turn off the heating or cooling in rooms that are unoccupied. Remember to turn off heating or cooling in office spaces that are not being used and when leaving.

Keeping your business temperature one degree down during winters and one degree up during summers can reduce the power it uses by up to 10%.

5. Cut down on paper wastage

Printers in the workplace are often overused. Most of the time, work can be viewed on screen, rather than on printed-out paper.

Employees should be encouraged to print only when necessary. Not only does this reduce paper wastage, but it also helps cut energy required to run the printer, which in turn reduces energy costs and extends the lifespan of your printer.

6. Install a smart meter

Smart meters provide you with accurate information about your energy consumption. You’ll be able to identify and understand your energy use and know exactly what you’re paying for when your supplier sends you a bill.

 7. Allow employees to work remotely

If possible, allow employees to work from home on alternate days. Employees can still be in contact with those in the office and it’s also likely that they will get more work done at home without the distractions that often occur in the office environment.

Technology allows employees to have flexible work arrangements, and by having fewer employees in office, less lighting, cooling and running workstations would be required.

8. Always check the energy label

The EU Energy label, rates products from A (the most efficient) to G (the least efficient.

Products that are required to display this label include: washing machines, washer-dryers, tumble dryers, fridges, freezers, dishwashers, electric ovens, energy-saving light bulbs and air conditioners.

9. Switch off or unplug any equipment that is not in use

Laptop and phone chargers continue to use energy even when the device is not attached.

During weekends and holidays, make sure to switch off office equipment that is not in use. This includes printers, scanners, microwaves, lights, air conditioners, and coffee machines.

Gadgets and appliances that are not in use can account for 10% of your electricity bill.

10. Consider solar panels

Solar energy is free, renewable and clean. Although the initial cost of solar panels is expensive, the cost is recovered within a few years if used to its full strength.

Solar panels last longer and have fewer maintenance problems. This helps cut monthly business energy costs.

Business leaders discuss how they cut down on energy bills

cut down on energy bills

Smart meter data shows that small businesses use 46% of their total electricity between 6pm and 8am.

A few simple changes could cut the office energy bill by up to 20%.

During The Business Show, UK’s largest business exhibition, business leaders revealed their best advice. They also discussed how businesses could cut down on energy bills and save costs.

Watch tips from some of the UK’s best-known business people – including Dragon’s Den’s Touker Suleyman, Brett Akker from Lovespace, Sage One’s Jonathan Dowden and Steven Bartlett from Social Chain – discuss how businesses can cut energy bills.
