‘Energy efficient’ windows will cost £15,000 but save lives and help curb CO2 emissions from the UK’s electric grid, report says
A new report shows that “energy efficient” windows and “electrical power” could save lives in Britain, but they would cost up to £15.7 million to install.
The study by the think tank Climate Investigations looked at the impact of installing solar panels on homes and businesses in the United Kingdom, where the cost of energy is rising as the UK transitions from a carbon-free economy.
The report’s authors estimate that installing solar and wind energy could save between £10.7m and £20.7million annually in electricity bills.
The cost of the windows, which are generally installed by contractors, could range from £20,000 to £100,000.
“It’s a big step,” said Professor Andrew Houghton, director of Climate Investigations.
“It is a big, big price.
But the benefits are enormous.””
The impact of solar and renewables on household electricity bills has been substantial, even in the midst of an economy that is in transition,” he said.
“This research shows that if we want to get to a low-carbon economy in the UK, we need to install more than we currently do.”
If we’re going to get there, we’ll need to reduce our carbon emissions and increase the supply of renewable energy.
“The report estimated that installing a solar panel on a typical house could cost between £1,500 and £10,000, depending on the size of the house and whether the panels are located in a “natural” or “green” location.
Solar panels installed in a green location would cost £7,000 and a natural location could cost £14,000 in energy cost.
Solar panels on a natural site could be installed for around £4,500.
A typical solar installation in the US costs between $30,000-$40,000 ($58,000-$92,000) and would require around 1,400 solar panels to provide the same amount of energy.
Solar power can also be installed on rooftops and in small “greenhouses” for energy efficiency, which is estimated to cost between $8,000 (0.4 kW) and $12,000 per square meter.
Solar and wind power would be cheaper in the country if installed on “natural”, or more “green”, sites.
In the US, it would cost around $3,000 (£2,000), which is equivalent to installing 2.5 solar panels, according to the US Energy Information Administration.
Solar energy is also cheaper in Germany, which costs between €1,300 and €2,400 per kilowatt-hour (kWh) for a typical rooftop.
A “natural site” for solar energy would be more expensive in China, which could cost up.
The authors said the UK should adopt the US model of “green energy” where people can buy energy-efficient products such as solar panels or other products such “green power”.
The UK is currently installing wind farms, solar panels and solar power, which “should be a national priority”, the report said.”
There are opportunities for the UK to lead the way in green energy, which can help the economy, save energy and reduce carbon emissions.
“Solar power is expected to be a big contributor to the UK economy, with around $40 billion (28 billion euros) of energy-related jobs in the next 20 years, the report found.
But there are fears that solar energy could be priced too high for the average household, as well as for businesses, as solar energy is already expensive to install and expensive to run.
For example, installing a roof-mounted solar array in the middle of a garage could cost more than £1 million ($1.8 million).
The report said the cost per kilo of solar energy will be higher for large installations than for smaller installations, because “the efficiency of the panels and their components, combined with the fact that the solar panels are highly variable, is difficult to predict”.
The report also found that installing more wind turbines on buildings could cost about £6 million per megawatt-hours (MWh), but would not lead to any energy savings.
The cost per megowatt of wind power in the USA was about $25 per MWh in 2012, and the cost in the European Union is estimated at $40 per MW.
