Barnet

Where ever you live in the UK from the far north to your location and all the way to the south, energy suppliers are a constant cause of stress and financial drain. We all want to pay less for our energy but with costs and tariffs changing all the time, it can be very difficult to make the right decision. This page will point you in the right direction for help in Barnet and much more.

When people are looking for ways to reduce expenses or make better use of their money, they often look at common household expenses like utilities, subscriptions and even those associated with entertainment and recreation. The biggest monthly outgoing is usually food and energy bills.

In order to get the best gas and electricity deals available you need to understand how the gas and electricity suppliers are set up and how they calculate your bills. Many people don’t have a clue about the structure of the utility market in the UK and as a consequence end up spending way over the odds for their heating and lighting.

If you are looking for a better deal on your utilities then it’s pretty likely you were not too happy with your last bill. Especially in these tough economic times, you need to make sure you are not paying more than you have to. Just recently there have been further reports in the press of how the wholesale price of fuels is coming down yet the suppliers are not passing on these savings to their customers.

The easiest way to find the best gas and electricity for your area is to use a price comparison website, this takes all the guesswork, sales hype and confusion out of the process and lets your quickly see who can give you a better deal. I have consistently found energylinx to get the best prices and I would recommend you check them out. Utility bills often have a high monthly price, and reducing your spending on this can mean having more money that you can allocate toward other things.

You might also want to consider downsizing your lawn by using more hard surfaces to reduce electricity use with your lawnmower. Or perhaps you use a timer for your winter heating when leaving the heat on at a low level has been shown to reduce consumption. Cooking individual meals for families that could eat together is also an energy waste that can be recovered. Installing solar panels can produce energy for use in your home but the amount generated and the saving made depends on the position of your home and the time scale you need to recover the initial outlay. New smart meters claim to save you money by making you more aware of the energy you consume each day. However, these are not available everywhere in the country and there have been some issues with the technology.

After covering saving energy used for cooking and heating water in your home or office, we can make the transition to reducing the amount of electricity used for refrigeration, washing and lighting. Remember, up to 25% of total energy consumption in a home comes from these three areas. But don’t feel overwhelmed. Here are a few easy to implement strategies that can save on energy bills going forward.

Start With Heating.

The lowest cost method for reducing consumption is utilising programmable thermostats. Every degree that you adjust by equal a 4–5% reduction in energy usage for that system. Also, don’t forget to program thermostats to turn on and off at the proper times and you will begin to see a reduction in usage. Add strip curtains and automatic door closers to walks ins and Installing ECM’s on evaporator and condenser fans can reduce usage by approximately 2/3rds. On the lighting side, you have options as well. Start by adding occupancy sensors in select areas such as closets, storage rooms, staff bathrooms, etc. Also adding high-efficiency LED bulbs can reduce lighting consumption by up to 50%. Many utilities will cover a percentage (my local utility covers up to 70%) of the cost to purchase the bulbs, significantly improving ROI.

By implementing these simple strategies we have covered, you are well on your way to energy savings by reducing consumption which is a key element in any energy management plan.

How Can Small Businesses Save on Their Energy?

Lucy Symons, Director of Public Policy at Open Energi calls on policy makers to make regulation fit for purpose

This winter, the UK is expecting high demand for electricity supply and an increase in costs. Renewable power sources are starting to fill the gap left behind by closing coal power stations, but they generate more when the sun shines or the wind blows and are not necessarily available when people turn on their televisions in the evenings.

National Grid pays gas and coal plants and diesel farms to turn up or down their supply whenever there’s an increase or decrease in demand for electricity. This winter alone, keeping power plants going for peak demand is forecast to cost consumers £122 million, while an estimated £800 million in subsidies may be awarded to diesel projects under the Government’s Capacity Market. This is expensive, slow and not very green. Energy prices and security of supply are top political priorities, but when it takes four years and a lot of money to build a power station, there needs to be a more efficient solution.

The good news is that Great Britain has a thriving energy technology sector with a vast portfolio of innovations that can step up to this immediate challenge. Open Energi, a dynamic UK tech firm, uses technology to link together more than 3,000 machines — like air conditioners in your local supermarket or the pumps moving our water — and switches these machines on or off during the day to make power available when it’s needed by consumers, or to store electricity after a big gust of wind. This technology is already installed at over 350 industrial and commercial sites across the UK including Sainsbury’s, Tarmac, Aggregate Industries, United Utilities and University of East Anglia. Developed right here in Britain, this is powerful technology. On cold winter evenings, it can function just like an entire nuclear plant. Demand flexibility is the first line of defence in an energy security crisis, which is characterised by successive power plant failures rather than a lack of supply.

But this ‘demand-side’ energy tech faces major barriers in UK energy markets. Companies like Open Energi cannot prequalify for the government Capacity Market and cannot compete directly against gas plants in the balancing mechanism. The fast, flexible power they provide is instead only accessible via monthly tenders and procurements. Faced with a national energy security crunch on one hand and with the tech needed to solve it bound only by markets that aren’t fit for purpose, there is an immediate opportunity to unleash competition. Unlike other energy projects, demand flexibility requires no state subsidy at all. All that we ask at Open Energi is that the regulations are updated to ensure ‘demand side’ (when we turn demand up and down) is given the same treatment as ‘supply side’ (when new power is generated) in the existing energy markets.

Deploying demand flexibility and storage at speed to solve an energy crunch at scale is a proven path. In 2015, Californian policymakers were faced with a shutdown at the state’s biggest gas storage facility, threatening peak shortages and blackouts. To solve this immediate challenge with an immediately available solution, policy-makers fast-tracked 64.5MW of electricity storage and approved $11.5 million for demand response and dynamic pricing. Energy storage projects were constructed in less than four months, compared to a previous average of three and a half years.

Applying the same market mechanisms in the UK could dramatically change the game for energy security on the GB grid as early as next winter. With over 1GW of energy storage prequalified for National Grid’s recent Enhanced Frequency Response tender, of which only 200MW was purchased, it’s clear we have the appetite from investors to bring innovation to market. The challenge now rests with policy makers to make regulation fit for purpose in a modern age of energy technology innovation.

Lucy Symons is the Director of Public Policy for @openenergi and recently travelled to California as part of a delegation of female founders leading some of the UK’s fastest growing tech firms.

What is Electricity?

Essentially, there are two kinds of Electricity: Static Electricity and Current Electricity. Both depend on electrons, the tiny charged particles that orbit the nucleus of an atom.

Static Electricity has been known about since earliest times, though it was not properly understood until the discovery of subatomic particles a little over a hundred years ago.

Static Electricity on a large scale causes lightning and on a much smaller scale can give you an annoying shock when you step out of a car. You can generate it simply by combing your hair with a nylon comb. The electrical charge transferred to the comb will cause it to attract the hair, or, if you like, to pick up little scraps of paper to entertain the kids.

Though interesting, static electricity is of limited practical use. For the remainder of this hub, we'll concentrate on current electricity which is a flow of electrons through a conductor (usually a copper cable).

The Modern Alternator

Faraday's electrical machines were laboratory experiments. Technology has developed his ideas dramatically. The modern alternator does not use permanent magnets but an energised coil instead, to produce the magnetic field. Also, his invention has been turned inside out, with the field coils mounted on the armature (now called the rotor) and the electrical current induced on the stationary coils (the stator). There are normally three stationary windings in the stator, spaced 120° apart, to produce 3-phase alternating current, the modern standard for distribution.

A Little Science

But first, we need to talk a bit about Energy. In Physics, Energy is defined as the ability to do Work. (Everyday examples of Work are: climbing stairs, loading a truck. anything that involves moving mass).

Some of the common types of energy are: heat, light, kinetic energy (movement), chemical energy, gravitational energy and of course. electrical energy.

In Physics, the Law of Conservation of Energy says that energy cannot be created or destroyed. It can only be transformed from one type to another. This means that to generate electricity, we have to use another kind of energy to fuel the process - in this World you don't get something for nothing!

Michael Faraday

In the 19th Century, Michael Faraday carried out the pioneering work that linked Electricity and Magnetism. In particular, he showed that an electrical current is generated in a conductor moving in a magnetic field.

The effect is greatly magnified if the conductor is replaced with a coil or coils of copper wire. If these coils are mounted on a rotating shaft or armature, continuous rotation will produce a continuous alternating electrical current. This is how nearly all electricity is generated today.

Now that we have a device (the generator, or alternator) that converts mechanical energy (rotation) into electrical energy, the next problem is how to obtain the mechanical energy to keep the alternator spinning. Here is a brief summary of some of the viable ways of generating electricity on a commercial scale.

The Commercial Options

Fossil Fuels

In a coal or oil fired power station, the fuel is burned (converting its chemical energy into heat) and the heat used to convert water into steam at very high temperature and pressure. This then drives a steam turbine, a device which harnesses the energy in the steam (heat and pressure) to produce rotational movement (mechanical energy). The rotating shaft of the steam turbine is coupled to the armature of the alternator, so the final result is electricity.

Wind Power

Windmills have been around for centuries and all have harnessed the energy of moving air (wind!) through rotating sails or fan blades. Traditionally, the mechanical energy was used directly, to turn a mill wheel. A modern wind turbine simply couples the rotating shaft to an alternator armature. The last link in the chain is always the same - electricity from mechanical rotation.

Hydro Electric Power

Here, the source energy (there always has to be one!) is gravitational potential energy. A mountain stream is dammed in a high place, to create an artificial lake or reservoir. Farther down the mountain, the power station is equipped with water turbines. These are simply highly efficient versions of the old fashioned water-wheel; effectively they harness the kinetic energy of a carefully channelled waterfall to produce mechanical rotation. The rest you know.

Tidal Power and Wave Power

These new technologies extract energy from the long-term bulk movement of water in a tidal estuary and from the short-term wave motion of the surface. The principle remains the same, to harness the 'free' natural energy in moving water to drive a mechanical turbine.

Solar Power - local

In a sense. all energy on Earth is solar energy, as even fossil fuels are chemical 'memories' of ancient sunshine. But we're talking here about generating electricity from solar energy, and strangely enough, it's not very easy. The problem is that you can't easily convert sunshine into mechanical rotation to drive alternators on a commercial scale. Solar panels have no moving parts, and so the electricity they produce is 'DC' or direct current. This is like the electricity from a battery. It's great for local use, e.g. running a small irrigation pump, but the big problem with DC is that it is hard to distribute. (No time to explain that now - maybe another hub!)

Solar Power - commercial

Photovoltaic units, as described above, are best suited to localised applications like space or water heating. However, commercial-scale solar power plants, though still expensive to build, are becoming viable, the more so as the price of fossil fuels increases.

No single design for commercial solar power has yet won through, but all are based on the same idea - a large array of reflectors to collect the sun's rays and focus them onto a receiver which is effectively pipe-work containing a heat-absorbing fluid. Technologies are already well developed to store the collected energy as heat and to convert it to electricity using steam or gas turbines at a steady rate, night and day. The biggest problem is that the sun moves (OK, the Earth rotates!) and so ingenious tracking mechanisms are needed to make the reflectors follow the sun through the daylight hours.

Ironically, the part of the world best suited for deploying this technology is the part that least needs it - the oil rich deserts of the Middle East.

Geothermal Energy

This is another underdeveloped source. If you drill down into the Earth's crust, at first the temperature drops, because the sun's warmth can't penetrate. But deeper, the temperature rises. Volcanoes are evidence of this - molten lava is pretty hot! That well of energy is there to be tapped. As always, the final conversion process is the familiar steam turbine. And, like solar energy, it is environmentally friendly, provided you don't accidentally trigger a local volcano! But it is not as simple as it seems. The process of taking heat from a hot rock cools the rock locally. There's plenty more heat surrounding it, but can it flow quickly enough to your collectors? Again, it's another technology whose time will come, but not a panacaea.

Nuclear Energy

This is the controversial one. Nuclear fission is a process in which unstable (radioactive) atomic nuclei break down, releasing energy in the form of radiation (escaping particles). By concentrating these nuclei together, a controlled chain recation is produced releasing huge amounts of energy which is used to convert water into steam. The process of generating electricity in a nuclear power plant is simply by steam turbine, exactly the same as in a fossil fuel plant. The public fear of nuclear power is twofold: the risk of meltdown - an uncontrolled nuclear reactor is not very different from an 'atomic' bomb; also the by-product, radioactive nuclear waste, is none too pleasant.

As an aside - Nuclear energy does not obey the classical Physics law of conservation of Energy. It does however obey the Modern Physics law of conservation of Mass-Energy which allows for interconversion of matter and energy according to Einstein's famous equation E=mc² This fundamental difference means that Nuclear Energy is potentially the most fruitful source of all. It is important that proper scientific research & development into nuclear energy, and Nuclear Fusion in particular, should be allowed to continue.

If your local Utility company is one of the big six energy suppliers you probably aren’t getting the best deal possible. Most of the cheaper tariffs are offered by smaller, often unfamiliar companies. These are typically hidden or don’t feature prominently on the major energy comparison websites that compare the market.
