Compare The Market Gas And Electricity Prices South Acton Ealing

For many Londoners, the cost of living is already very high. Monthly energy bills for their gas and electricity are unavoidable but switching regularly can reduce those outgoings significantly. Comparing your last year’s bill every twelve months might seem like a chore but it could pay for your holiday each year if you play your cards right and do the leg work. It really doesn’t take that long, especially if once you’ve done it a few times. Find your favourite comparison site covering the South Acton area and set a yearly reminder on your phone. Then act on it each year to make the most saving possible.

To find the lowest tariff you might need to look at your gas bill and your electricity bill separately. This is easier than you might think at first. Ove you’ve selected the best tariff for both services your gas and electric bills will be lower and you can start to plan that summer holiday.

More Energy Saving Tips

As we all know running the home central heating during the winter months can be expensive, but did you know there are some simple things you can do that can help bring down those costs. Your central heating boiler is an essential part of your home, it supplies you with unlimited hot water when you need it, and it keeps you warm in the colder months.

First, make sure that you have your boiler serviced each year, preferably before the winter kicks in. Your central heating boiler is just like a car engine, if left unserviced, over time things will start to go wrong, the same goes for the central heating boiler.

If your central heating boiler is not serviced and something is starting to go wrong your energy bills will start to rise, your boiler may need to work harder to reach that desired temperature thus higher bills, if the boiler is maintained and checked over, anything that needs adjusting or replacing can be carried out.

Another simple way to save money is to make sure the radiator itself has nothing around it, keep it clear so the heat can penetrate the room, don’t put clothes that you want to dry on the radiator put them on a clothes horse close by they will still dry. When you put clothes on the radiator all the heat is lost into the clothes and the room takes longer to heat up. Pipe insulation is another way of cutting down those energy bills. Any pipework that you can visibly see should be insulated. By fitting insulation to the pipes you are reducing the heat loss from that pipe, you can buy pipe insulation from the local DIY store.

These are just a few of the ways you can save on those central heating bills, and remember when you have the central heating boiler serviced, only use a registered gas safe company or engineer.

Now that you’ve saved money on your gas and electricity bill why not look at the other monthly costs that eat into your usable reserves and save even more money each month.

There is a long way before EVs become mainstream but there is clear sign of growth and clear steps for us to take action to accelerate the market.

Electric vehicles are zero emissions during its use. They need to be recharged by connecting it to an electricity supply and so the CO2 impact depends on how green is the grid electricity. Electric vehicles will be better for local air quality as no emissions are produced by the car, except generation of electricity which will likely be from a power station.

This brilliant analysis by CarbonCounter by MIT helps us understand each car models against climate targets. Lifetime cost of each vehicle per mile driven is compared against greenhouse gas emission target of 2 degrees C global warming.

Lifetime costs of EV in yellow vs Internal Combustion Engine Cars in black (http://carboncounter.com/)Our results show that you don’t have to pay more for a low-carbon-emitting vehicle. Many electric vehicles are the same price, or cheaper, than similar gasoline cars. The average greenhouse gas emissions of all cars shown here are more than 50% higher than the 2030 climate target, with no internal combustion vehicles meeting the target. Most hybrid and electric vehicles, on the other hand, already meet the 2030 goal today, with today’s electricity mix.— CarbonCounter.com MIT Trancik Lab

Buying EV

With nearly 1 in 6 people in Europe considering buying an electric vehicle, there are more options available and a growing number of services becoming available. There are calculators to help compare electric vs petrol/diesel fuel cost and websites to guide you through comparisons of different electric vehicle such as Next Green Car.

EV Charge Points

We have seen the growth of apps for EV charge point maps such as Zap-Map, PlugShare, and Open Charge Map. Plug share is mainly based in the US and Canada. Zap-Map has the most comprehensive map of the UK. Open Charge Map is a global non-commercial, open source project.

They each have communities of EV drivers using the apps. Data source varies but they mainly crowdsource charging point information from their community of EV drivers onto their map or partner directly with networks of charge point providers or installers to list the charge points.

Zap-map provides a comprehensive comparison of charging networks and their cost structure. For instance, Ecotricity provides green electricity on their network of Electric Highway. Tesla provides Tesla Model S and Model X owners free access to their network. Most network would require a RFID card for payment and access to the charge points. The networks too have their own apps.

These aggregated charge point apps generally allow you to selects or register your electric vehicle and helps you find the charging points that are compatible to your vehicle. They will also display live data on the of availability or status of the charge points and can allows reporting to the owners if faulty. Charge points vary by type charging speed (slow, fast, AC, DC) and connectors. Users can even add photos of the charge point to the app and rate and review the charge points.

EV Rentals

For people who are not EV car owners but may want to enjoy a zero emissions journey, there is the option of EV car clubs.

E-Car is UK’s first entirely electric pay-per-use EV car club in the UK, now part of Europcar. They offer last minute self-service booking via their app and you can access the car by holding the membership card on the windscreen and the door unlocks. They operate a mixed-use model and partner with business parks, local authorities and universities. They are also the world’s first equity crowdfunding exit when acquired by Europcar in 2015, proving a great success for the cleantech crowdfunding market.

Other alternatives include Co-wheels Car Club which is a social enterprise with a bigger fleet of low-emissions electric cars, hybrids and vans for rental.

The benefit of allowing people to try out a range of electric cars is that this will encourage people to buy electric cars which will help accelerate the move towards EV.

EV Taxis

For those who are not into the driving, there are services out there to access EV. Gliide is a London-based taxi service apps that work with a fleet of Teslas. Thrive another taxi service app operates with a fully electric vehicle fleet composed of Chinese manufactured EV’s BYD. Bookings and payments are done via the app. Newcomers Hoopoe-Electric also operate a small fleet of Teslas.

EV Secondary Market

We can also expect the rise of the secondary market for EV-related items. Online marketplaces such as Eco-Car.net where people buy and sell EVs and related accessories such as EV cables will continue to grow, not to mention the emergence of the second hand EV battery market when this battery capacity becomes not road worthy but good enough to be repurposed for home energy storage e.g. Project Aceleron.

So let us know what you think of the EV market. Are there any new EV related services that you have seen?

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.
