Because coal-fired power stations are so obviously bad for the environment and electricity so profligately used, governments have been quick to hand out environmentally friendly regulations to its generators and suppliers.
An integrated power company in the UK must now, by law,
a) increasingly source its power from renewable energy
b) undertake a certain level of activity to improve energy efficiency in households,
c) pay a fixed reward to consumers producing their own renewable electricity (so-called 'feed-in' tariffs) and d) ensure their total emissions stay within a fixed cap (or buy in emissions reductions from elsewhere to compensate).
Soon they will also be required to collect a levy to be spent on capturing and storing carbon underground. It may not be long before they are also obliged to go nuclear.
All this regulation is absolutely essential for driving investment in climate solutions but it makes the act of choosing an electricity tariff considered 'greener' than average almost impossible. The good news is that by the time electricity reaches us it's already got all the legal green obligations priced into it. So we are all doing our bit via our bills already. But if you don't think the government's obligations are going fast or far enough and want to exercise your consumer power to go further, it quickly gets complicated trying to work out if that thing you want done is really additional or just meeting a legal requirement.
Ofgem's new trademarked label for green electricity tariffs is a welcome step forward. Help is at hand for the consumer seeking to navigate this carbon policy jungle.
A new panel of auditors has taken Ofgem's guidelines, issued last year, and scrutinised proposed green tariffs wishing to bear the new trademark – those that have passed will be announced today. The crucial test: is this product doing something that wasn't required of the electricity company already? Broadly, three things qualify – investing in (but not owning) community renewables projects too small to be part of the renewables obligation (point a. above), paying for energy efficiency projects that do not qualify for the existing requirement, and buying and cancelling emissions permits that would be otherwise used to allow pollution to carry on.
Of these, by far the easiest to audit and most clear in terms of doing something new, is the last: permit cancellation. The Environmental Audit Committee report, issued yesterday, clearly recommended that caps on emissions, in the UK and Europe, be significantly tightened. This must ultimately be achieved by changes to the policy at EU level but it can also be helped along by action by member states and by consumers.
Fewer permits in circulation mean less pollution. So tariffs that cancel them are good. More investment in renewable power and electrical energy efficiency unfortunately cannot be guaranteed to do the same unless some of the fixed supply of pollution permits are also cancelled. If they are not, they will be sold to someone else who will use them to pollute.
This fact has long been ignored in Europe though it has been the subject of intense debate in Australia, where the government is trying to introduce caps on emissions, and has already been addressed in the existing US regional cap and trade scheme. This has to change.
The Ofgem guidelines go a long way towards untangling the many overlapping climate policies that now exist. They are not perfect and there is still a long way to go to increase awareness and make the distinction clear between cancelling pollution permits and the much-criticised use of 'carbon offsetting', which is not the same thing.
If this can be achieved and more policies and products be aligned so that we get the number of permits in circulation down, then this new scheme will be an efficient way to harness green consumer power.

URBAN ENERGY:
Switching to energy suppliers that have the Ofgem badge is a great start, but why not produce your own electricity & hot water by installing solar photovoltaic (pv) and solar thermal panels? Become a microgenerator, and get paid by the government to do it!
URBAN ENERGY THERMAL:
Solar panels are typically located on the roof of your house or commercial property. These panels are able to convert everyday sunlight into heat energy stored within a cylinder, where it can be used to provide hot water for your home or business.
URBAN ENERGY SOLAR ELECTRICAL POWER:
Photovoltaic (PV) panels can be installed ‘on’ or ‘within’ the roof of your commercial property or home and are designed to convert day light into usable solar electricity. The solar electricity generated will be able to power any electrical device within the building without compromising quality of delivery. Their Photovoltaic panels have been designed to work within a grid system to permit the sale of redundant electricity to power suppliers, eradicating the need for unnecessary and costly battery systems found on other types of installations.

The Sun’s Abundant Energy
It is often underestimated the amount energy which can be harnessed from the sun’s radiation. In the UK, we receive a vast amount of solar energy. In an average year we receive as much as 60% of the solar energy which is received on the equator. In other words, this can be compared to the yearly output of 1,000 power stations. It is often argued that solar technologies can only be used within the summer months, this is untrue. In fact, the UK has a large number of clear spring, autumn and winter days, where the Sun’s radiation can be harnessed, meaning that solar technologies can contribute to energy consumption for the whole year.
The total average solar irradiation falling on a one square metre surface on the horizontal (the sun's rays falling on the ground), measured in kilowatt hours (kW-h) ranges from more than 1200 kW-h m2 in the far south west of the UK, to less than 900 kW-h m2 in central and northern Scotland.
By tilting a surface to an angle the amount of solar radiation falling on it will be greater than that falling on a flat surface. Fortunately, in this country, the average tilt of a UK house roof is about the optimum for receiving solar energy.
By using the Sun’s abundant energy, we can reduce our consumption of conventional fuels thus reducing our emission of harmful greenhouse gases, as well as gaining enhanced fuel security and cost effective savings.

WATTS? & KILOWATTS?:
A human climbing a flight of stairs is doing work at a rate of about 200 watts.
A typical passenger car engine yields a power output of 25,000 watts while cruising.
A typical household bulb has an average power rating of 60 watts.
The kilowatt (1 kW) is equal to one thousand watts (1000 w). It is typically used to state the output power of engines and the power consumption of tools and machines. In old money, a kilowatt is approximately equivalent to 1.34 horsepower.
The average annual electrical energy consumption of a household is about 8,900 kilowatt-hours (kW-h = see below explanation), equivalent to a sustained average power use of about 1 kW.
The kilowatt hour (kW-h) is commonly used by power companies for purposes of billing, since the monthly energy consumption of a typical residential customer ranges from a few hundred to a few thousand kilowatt hours.
One kilowatt hour = 1 kW-h = 1000 watts per hour, is the amount of energy used if work is done at a constant rate of one thousand watts for one hour.
Megawatt hours (MW-h), Gigawatt hours (GW-h), and Terawatt hours (TW-h) are often used for metering much larger amounts of electrical energy to industrial customers and in power generation.
kilo = thousand: 1000 watts = 1 kilowatt = 1kW

Solar Thermal (Hot Water) Systems
Solar thermal (hot water) systems can be extremely efficient, reducing costs and energy consumption. For a solar system to work, all they need is daylight as they can collect both direct radiation, direct sunlight on clear days, and diffused radiation, light which is present on cloudy days.
Both flat plate collectors and evacuated tube collectors have selective and non selective surfaces. In terms of which collector has best efficiency, it is dependant on your domestic use. At low temperatures the efficiency for all the collectors is very similar, but as temperatures increase all the collectors show a slight reduction in efficiency. For lowest temperatures an unglazed non-selective surface flat plate collector can be seen as most effective, hence they are commonly used to heat swimming pools, however for highest temperatures there is a very marginal difference between selective surface evacuated tubes and selective surfaces flat plate collectors, with the former being the most efficient.
In terms of costs you would expect to save between 50 -70% on your annual heating costs, as the more hot water used the greater the saving. For a family of four, a well designed solar water heating system should contribute around 1,500 kW-h and 2,000 kW-h, which will be equivalent to 50 to 65% of the household’s water heating energy needs.

Greening Britain's Energy Supply
A fortnight ago Ed Miliband, the Climate Secretary, confirmed generous payments for home solar panel and wind turbine systems.
This scheme could transform Britain's poor record on renewable power. At present only 5 per cent of UK power comes from renewable sources, while 2 per cent of energy customers are on "green" tariffs. So will this initiative lead to low-carbon power for the people – and what's in it for you?
First, don't bother generating your own electricity or buying a "green" tariff until you have stopped energy leaking from your home; it's like pumping fuel into a car without fixing a hole in the petrol tank. Put plastic strips round draughty windows and reflective paper behind radiators, lag lofts to 27centimetres and fit eco-lightbulbs in every socket.
From April, a "Feed in Tariff" will guarantee payments to homes with solar panels and other micro-generation. A "well-sited" 2.5kWh PV solar scheme, the Department for Energy & Climate Change (DECC) says, should earn £900 a year and £140 in energy savings. And the financial case for going solar may improve if, as expected, banks offer renewable power loans later this year.

Employment in Renewable Energy Sector Could Rise to 500,000!
Energy minister David Kidney has claimed that the Renewable Energy Strategy, combined with a growing market for renewable energy globally, could increase UK employment in the renewables sector by up to a further 500,000 people by 2020.
The statement was made in the House of Commons earlier this month when Mr Kidney was asked to provide details of how many people have been employed in the renewable sector since 2003 and what recent assessment he has made of the potential for the creation of new jobs.
Mr Kidney replied that although there will be some displacement as the UK restructures its economy, the Renewable Energy Strategy would create significant job opportunities. He estimated that in 2007/08 up to 390,000 people were employed in the sector and that this could increase by up to a further 500,000 people by 2020.
