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 Palmers Green 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.
Energy suppliers are feeling increased pressure from the government to regulate and lower the cost of their fuel prices, after three of the big six energy suppliers have raised their energy prices once again by 20%.
The companies have all blamed the rise in gas prices on the rise in the wholesaler's prices.
The first thing to understand is that these companies we pay for our gas and electric bills, rarely produce the energy themselves. Like any other retailer, they buy their product from a wholesaler.
Q: If we check how much wholesalers are selling their fuel for, will it show if energy suppliers are justified in their high fuel prices?
If only it was that simple!
There are a lot of energy prices on the market, and they change every day, therefore the cost will differentiate when supply and demand goes up and down.
Wholesale prices are set at which period or season they are selling for. For example, a wholesaler and energy company may strike up a deal called 'winter 2017'. The energy firm is agreeing to buy gas to be shipped to them throughout October to March.
More expenses and pay outs are unlikely to do the economy any good.
Q: why doesn't the existing competition lower prices anyway?
Tariffs are still likely to mirror each other. Every time one supplier announces a price hike, it becomes easier for others to do the same, similar to how the cost of petrol can fluctuate so easily.
What you have to remember is that the 'big six' energy companies are trying like the rest of the economy, to make money, and that they'll be playing the field to get the best prices and stay on top of the market just like any other profit driven firm.

So you want to know how to save money on energy bills? Well, the first and most popular way people tend to inflate parts of an energy bill is excessive ignorance. It's simple. People are ignorant when they drive, when they use certain systems at home, and when they use energy in general. The very first thing you must conquer is the amount of energy you do. The mindset is where it starts.
Another thing you'll want to invest in is your own solar grid or windmill to capture your own solar and wind energy. Don't know how? No problem. Earth4Energy can teach you. It's a guide that shows you more than enough ways to cut your energy costs up to 90% and save you thousands of dollars. You will be able to build your own solar grid and windmill. After reading this guide, it wouldn't be so hard.

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!
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
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.
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.
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.
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.
