Usain Bolt will take to the global stage one last time at the London 2017 World Championships, bidding to crown his track career with more gold medals.

Bolt wants to go down in history as ‘unbeatable’ as he prepares to say goodbye. The Jamaican sprinter plans to run in the 100m final and 4x100m relay at the IAAF World Athletics Championships in London.

Bolt’s fastest time was in Berlin, where he ran the 100m final in 9,58 seconds. The infographic below illustrates how much energy Usain Bolt generated in this time.

Tampering with gas meter takes backfires

tampering with energy meter

Recently 4 take away stores in Birmingham were discovered to be running on tampered meters, after the person responsible reported one of the meters because it had caught on fire.

The customer was then linked to other sites through Land Registry and our data team. A total of 4 sites were identified, with 8 tampered meters.

Police are now handling the investigation and progress towards prosecution is taking place.

If found guilty, the customer could be issued with a bill amounting to £100,000.

The below image shows that the teeth of the meter have been cut, allowing 50% of gas to pass for free.

Tampering with gas meters is incredibly dangerous and can result in severe injuries or even death.

Illegally modifying your meter can result in jail time – as it puts the lives of others in danger from a possible gas explosion.

Wimbledon: How much energy can tennis pros generate?

Wimbledon_tennis_energy_generated

Wimbledon is the oldest tennis tournament in the world and has been held at the All England Club in Wimbledon, London, since 1877 and is played on outdoor grass courts.

Wimbledon is one of the four Grand Slam tennis tournaments, the others being the Australian Open, the French Open and the US Open.

Since the Australian Open switched to hardcourt in 1988, Wimbledon is the only grand slam tournament that is still played on grass.

There’s a lot of energy generated at Wimbledon, from crowds cheering in the stands to the tennis pros on the court burning a hefty amount of calories.

In fact, both men’s finalists will burn more than 2100 calories on average, an energy output of over 2.50kWh.

So what could this energy achieve if it was used to power your electronics and household appliances?

A year of using your computer or laptop racks up a fair amount of electricity, especially if you’re using your system for both work and entertainment.

On average your laptop computer uses between 50W – 100W when in use. Harness the power of 7 men’s finals and you would have enough energy to power your laptop for a year!

WIMB

LED light bulbs can last anywhere from 20,000 to 50,000 hours, or up to five times longer than traditional bulbs on the market.

Just 5 men’s finals could keep an LED lightbulb shining for more than 2 years.

WIMB2

The women’s final generates more than 1.50kWh, which is enough to keep your iPad charged for a whole year.

WIMB3

A regular sized microwave will use between 600W to 1700W depending on the model. To keep the microwave powered for a year, it would require energy from 70 men’s finals!

WIMB4

Time to turn up the power! An entire singles tournament at Wimbledon comprises of 127 matches. So, if you took the energy from every Wimbledon men’s game, you would have enough energy to power your fridge, vacuum cleaner and TV for an entire year.

WIMB5

The great thing about manpower 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.

Toyota Mirai: Everything you need to know about the hydrogen car

toyota-mirai

The Toyota Mirai uses of hydrogen – an important future energy source – to generate power.

The vehicle mixes environmental performance, with the convenience and driving pleasure that is expected of any car.

The Miraiuses Toyota Fuel Cell System (TFCS), which features both fuel cell technology and hybrid technology, and includes Toyota’s new proprietary FC Stack and high-pressure hydrogen tanks.

The car is much more energy efficient than internal combustion engines and emits no CO2 or pollutants when driven.

Drivers can also expect the same level of convenience offered by gasoline engine vehicles, with a generous cruising range and a hydrogen refuelling time of about three minutes.

Are Hydrogen fuel cell cars safe?

Hydrogen cars are perfectly safe. According to the Canadian Hydrogen and Fuel Cell Association’s website, “Hydrogen has been proven to be as safe as or even safer than other flammable fuels such as gasoline or natural gas.”

The precaution however is that, “…hydrogen can leak easily and ignite at relatively low temperature.”

The 2017 Toyota Mirai has proper safety features in place, which are described in a four-point process on how to keep the hydrogen from exploding:

  • Leak-proof tanks hold the hydrogen
  • In case of a collision, sensors stop the flow of hydrogen
  • Any leaked hydrogen is quickly dispersed
  • Hydrogen escapes safely into the atmosphere

 
Hopefully, these safety measures will change the minds of those who are unsure about hydrogen fuelled cars.

Toyota Mirai Features:

E performance:

The vehicle features a fusion of fuel cell technology with hybrid technology. The system uses Toyota-developed components including the Toyota FC Stack, FC boost converter, and high-pressure hydrogen tanks.

Toyota FC Stack:

The new Toyota FC Stack achieves a maximum output of 114 kW (155 DIN hp) and a world-leading power output density of 3.1 kW/L (2.2 times higher than that of the previous Toyota FCHV-adv limited-lease model).

FC Boost Converter:

A new compact, high-efficiency, high-capacity converter has been developed to boost power generated in the Toyota FC Stack to 650 volts.

High-pressure Hydrogen Tanks:

Tanks with a three-layer structure made of carbon fibre-reinforced plastic and other materials are used to store hydrogen at a very high pressure of 70 MPa (70 megapascals, or approximately 700 bar).

The Japanese car manufacturer is offering three years’ of complimentary fuel or $15,000 worth of hydrogen. New Mirai owners, or lessees, will be provided with a debit card, which they can use at fuelling stations.

You’re not going to find a hydrogen station as easily as a gas station, however, if you do find a hydrogen station, it will only take about five minutes to fill up. On just one refuelling, you’ll be able to travel approximately 312 miles.

£4 billion cost-saving energy investment opportunity

gab elf

A survey by British Gas business identified the barriers to energy investment and a £4bn cost-saving opportunity.

British Gas was the headline sponsor of the Energy Live Future conference at the Leicester’s National Space Centre, which took place on 7 June.

The event attracted more than 200 of the UK’s largest energy users, experts and innovators who shared their views on the future of energy with Gab Barbaro, Managing Director of British Gas business.

Both businesses and public sector organisations expressed their concern that political uncertainty and difficulties gaining boardroom approval are presenting major barriers to making energy investments.

They also described the growing pressure to reduce costs and convince senior management about the need to take control of their energy needs.

More than a third (38%) of delegates at the event, agreed that reducing energy costs remained the central energy issue for large organisations. This was closely followed by the challenge of convincing business leaders to allow investment in new technology (35%).

Nearly half (48%) of delegates suggested that political uncertainty, caused by the General Election, Brexit and changing regulation, could make it even more difficult for them to make significant energy changes.

Despite these challenges, British Gas business urged UK businesses and the public sector to embrace the disruptive trends and technologies that are transforming the UK’s energy landscape, as they present a unique opportunity for large energy users.

Barbaro said: “My challenge to business leaders is to get smart and be more proactive about their energy use. Businesses must think long-term rather than be swayed by current political or economic uncertainty – there are countless opportunities for organisations to save money on their bills today, by getting to grips with how it’s being used and taking action where it’s being wasted.”

When asked what would be the biggest energy trend of the coming decade, more than half of delegates (56%) believed that battery storage would be most important, followed by using demand-management technology through the Internet of Things (31%) and generating all of your own energy from on-site generation (12%).

space centre

British Gas business showed delegates how to overcome their energy issues by adopting three principles:

1. Smarter buying of energy

2. More intelligent use of energy resources

3. Greater control over energy use through initiatives such as on-site generation or demand management technology.

A variety of new and emerging energy technologies were on show at the event including the latest generation and storage products on offer to customers through Centrica’s Distributed Energy & Power business.

Several other influential businesses took part at the future-gazing event, including Microsoft, EY and Tesla. Delegates learned how to make use of block chain technology and the smart grid, and gave their verdict on current energy technologies during the ‘Energy Tech Tinder’ session.

Stephen Church, Partner at EY, said: “The industry is changing at a pace that has never been experienced before. This is the age of the empowered customer – and disruptive technology is at its very heart. Now the industry must rise to new challenges and embrace this change and disruption if it’s to make of the most of the ever arising new opportunities.”

A new record for renewables in the UK

Renewable Enegy UK

Renewable energy sources have generated more electricity than coal and gas in the United Kingdom for the first time.

According to a report from National Grid, power created from wind, solar, wood pellet burning and hydro supplied 50.7% of Great Britain’s energy on Wednesday 7 June, during lunchtime.

Add nuclear power to the mix, and by 2pm low carbon sources were supplying 72.1% of electricity in the UK.

These weather conditions on this day were perfect for renewables being both sunny and windy. Currently, records for wind power are being set across Northern Europe.

The National Grid tweeted: “For the first time ever this lunchtime wind, nuclear and solar were all generating more than both gas and coal combined.”

On the day before (Tuesday 6 June), a tenth of the UK’s power came from offshore wind farms – a first for the energy sector where cost dropped far faster than expected.

In fact, wind turbines generated so much power that prices dropped to a tenth of their normal level.

Emma Pinchbeck, who heads up renewable energy trade body RenewableUK, said: “National Grid is confirming that low-carbon sources are generating 70pc of our electricity – with wind power the star amongst these sources.”

She said the “incoming government should be proud of what the wind sector has achieved in the UK, and work with the industry to ensure that these record-breaking days for wind energy generation become our new norm”.

This is truly a milestone for renewables, and a step towards a low carbon economy.

Storage is of huge importance. For low-carbon sources such as wind, solar and hydroelectricity their efficiency is completely dependent on the weather.

The key is to be able to store excess energy produced – feeding it into the national grid as and when it’s needed.

The 10 leading European countries in renewable energy

Wind farm at sunset moment, Egypt

Climate change and the need to manage diminishing fossil fuel reserves are, today, two of the biggest challenges facing the planet.

In order to secure a future for generations to come, we need to reduce energy consumption and substantially cut down on greenhouse gases such as carbon dioxide.

Renewable energy technologies are clean sources of energy that will not run out. Ever. They also have a much lower environmental impact than fossil fuels..

Here is a look at 10 European countries where renewable energy is becoming an increasingly important part of the country’s energy mix.

10. Romania – 24.8%

Romania

Almost a quarter of Romania’s total energy consumption comes from renewable energy sources. The country surpassed its national target of 24 per cent and easily exceeded the European target of 20 per cent.

9. Lithuania – 25.8%

Lithuania

An important pillar of Lithuania’s energy policy, renewable energy accounted for 25 per cent of the country’s gross energy consumption. At the start of this year, Lithuania was home to more than 2,500 power plants from renewable sources such as wind, solar and hydro.

8. Portugal – 28%
 Portugal

Portugal has become one of Europe’s leaders in terms of renewable energy sources – specifically with wind and micro-generation.

7. Estonia – 28.6%

Estonia

Oil shale and renewable fuels meet a large part of Estonia’s energy needs. Renewable energy plants are becoming more available in the country, with 28 per cent of energy consumption coming from renewable energy resources.

6. Croatia – 29%

Croatia copy

Hydropower forms a huge part of Croatia’s installed renewable capacity with wind and solar power following behind.

5. Denmark – 30.8%

Denmark

Denmark relies heavily on wind power – with more than 31, 000 people working in the industry in 2015.

4. Austria – 33%

Austria

Austria is home to more than 2.4 gigawatts of installed wind capacity and 900 megawatts of installed solar capacity. However, hydropower is the largest supplier to the country’s renewable energy, contributing more than 13 gigawatts of installed hydropower capacity.

3. Latvia – 37.6%

Latvia

Hydropower and gas provide the majority of domestic electricity supply for Latvia, with wind and biomass also contributing to the energy mix. In 2014, hydroelectricity produced 39 per cent of the country’s total electricity generation.

2. Finland – 39.3%

Finland

Bioenergy, hydropower, wind power and ground heat are among the largest renewable energy sources in Finland.

1. Sweden – 53.9%

Sweden renewable energy

By quite some way, Sweden is the leading European country in terms of renewable energy, with over half of its energy supplies coming from renewable energy sources.

In 1970, 75 per cent of its energy supplies consisted of oil – this figure has now fallen to roughly 20 per cent today.

Champions League final: how much energy can players produce?

Madrid vs Juventus

This weekend Juventus face holders Real Madrid in the UEFA Champions League final at the National Stadium of Wales in Cardiff.

While the hype may be around the team line-ups and who will come out on top, have you thought about how much energy players will produce this weekend?

A game of football is characterised by intensity – short sprints are mixed between periods of walking, jogging and moderate-paced running.

Let’s take a look into this maximal intermittent form of exercise and see just how much energy football players will produce…

Intensity and distance covered

During a football game all three types of energy would be used, as intensity changes from low to high.

However, because it’s not clear just how fast, how many and how long the sprints are, as well as how easy and how long the intervening periods are, it’s not easy to determine which of the energy systems are most important.

In 1976, two English researchers, Thomas and Reilly analysed the patterns of football players in the old first division.

They worked out that a player would change their energy activity every 5-6 seconds, and on average would sprint for 15 meters every 90 seconds.

According to SportVU the average distance covered by a football player is 15km.

Thomas and Reilly found that of the distance covered over the 90 minutes, the average football payer’s energy could be broken down into the following intensities:

  • 25% walking – 3.7km
  • 37% jogging – 5.55km
  • 20% running (below top speed) – 3km
  • 11% sprinting – 1.65
  • 7% running backwards – 1.05

Calculating the energy used

If we take the average distance to be 15km over a period of 90 minutes with the average weight of a player being 70 kg’s – the energy usage per player would be 1575 kcal (6615 Kjoules).

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, 1,575 kilocalories would be 1.84 kWh. A team of 20 players (excluding the 2 goalkeepers and reserves) would generate 36.8 kWh.

What could these 20 players power?

Using the total of 36.8 kWh, 20 football players competing in the Champions League final could power:

  • A coffee machine for just under a year (if used 10 minutes everyday)
  • A microwave oven for up to 20 weeks (if used for 1,5 hours per week)
  • An LED TV for 7 months (if used 4 hours a day)
  • A low-energy light bulb (12W) for almost 3 years (if used 5 hours per day)
  • An electric shaver (8 -12W) for 123 years (if used 5 minutes every day)

Of course this is not an accurate measurement, as each player’s work rate differs. However, it does show the potential energy that can be created by footballers.

Human energy generation won’t save the world’s energy crises anytime soon, but they remain a foundation for generating clean energy in the future.

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

Volcano power plant can generate 10X more energy than oil or gas wells

Iceland's Thor volcano

Iceland’s “Thor” volcano can generate 10X more energy than oil or gas wells by tapping into liquid hot magma.

Geothermal energy is nothing new, but Iceland’s volcano will take things to a whole new level.

Named after a Nordic god, “Thor” is a rig that symbolises Iceland’s leading-edge efforts to produce powerful clean energy. Engineers plan to drill nearly 3 miles into the live volcano to tap liquid hot magma.

The extreme heat and pressure at this depth makes the water take the form of a “supercritical” fluid, which is neither gas nor liquid.

The aim is to generate electricity from the heat stored inside the depths of the volcano by creating steam that causes turbines to move and generate power.

The well is anticipated to be the hottest hole on earth, containing magma that averages 427 °C (800 °F). The hole, completed in January this year has begun production – and if successful, the clean energy source will be able to generate ten times more energy than standard oil or gas wells.

Albert Albertsson, an engineer at the Icelandic energy company HS Orka, involved in the project says; “we expect to get five to ten times more power from the well than a conventional well today.”

The geothermal well is expected to generate enough energy to supply electricity and hot water to the capital city of Iceland, Reykjavik, with a population of 212,000.

Usually, you would require 30-35 conventional wells to generate enough energy for a city of this size, however, if Thor performs as expected, it would only take 3 – 5 wells.

The volcano is situated not far from the Blue Lagoon – a stream attracting more than a million tourists last year.

Thor also overlooks craters formed by the last volcanic eruption that took place 700 years ago, covering part of Reykjanes peninsula with a sea of lava.

Scientists and engineers working on the “Thor” experiment have two years to determine its success and the economic feasibility of the drill project.

Summer energy tips: How to cut down on costs

Save on energy costs during summer

The summer season couldn’t be closer, and while you may be welcoming the warmer weather with open arms, your energy bills can quickly add up.

With temperatures rising, there are several things you can do to make sure that your energy costs don’t rise with the heat.

Here are some tips to help your business some money this summer.

Keep the cool air in

With the hot sun beating down on us, many businesses will crank up the air conditioner without second thought.

If you have an existing air conditioning system in place, you may want to think about servicing or repairing it to help keep the system running smoothly and efficiently.

Insulating your business premises doesn’t just keep the cold air out in the winter, it also prevents hot air from getting in during the summer. If using air conditioning, remember to keep windows and doors shut to keep the cool air from flowing out.

According to the Department of Energy, you can also save 10 per cent a year on your cooling bills by simply turning your thermostat back 7°- 10°F for 8 hours a day from its normal setting.

Service your boiler

Summer is the best time to make sure your business boiler is in good shape before winter. An annual service by a Gas Safe registered engineer should help catch any problems, keeping your business safe and warm throughout the year. If it turns out that your boiler needs a little more than just a service, it’s much easier dealing with it in summer when it is warm, when you’re not as dependent on it.

Preventing problems with your boiler helps avoid unnecessary hassles to your business routine. A faulty boiler could waste you money on energy and might even start leaking poisonous carbon monoxide.

Make the most of natural lighting

It may sound obvious, but many businesses still struggle to achieve maximum efficiency when it comes to office lighting.

Apart from using fluorescent bulbs that use around about 75 per cent less energy than standard light bulbs, you can make use of natural light coming into your office.

You may need to figure out where the sun will be and when, and rearrange the layout of your business space accordingly. Move desks around so that they are not in direct line with the main window when the sun is beaming in throughout the afternoon. This way you can keep your blinds open and your lights off.

What else?

Here are some easy other ways you can help feel more comfortable during the summer months:

  • If there is a heatwave, relaxing business dress may help staff morale
  • Using a fan can help increase the efficiency of an air conditioning system
  • Turn off anything which creates heat when not in use, such as printers and monitors
  • If you’re not making use of air conditioning, open windows and doors to prevent stuffiness

Many business leaders tend to pay more attention to their energy consumption during the winter months, however for every pound that they save on lower heating bills, they’re likely to be spending the same amount, if not more on air conditioning.

Also, don’t assume that you have to wait until the winter before you take serious control of your energy usage. Start today!
