Can I have a business energy contract if I work from home?

Wind turbines have become a relatively common site in Britain’s rural landscapes. The distinctive shape is crucial to the functioning of traditional turbines, the turning of the blades capturing kinetic energy and turning into electricity.
Unfortunately, it also creates noise, including low frequency sounds that can cause adverse health effects in humans. The moving parts mean that turbines need regular maintenance, an important consideration given the significant initial expense of turbine manufacture.
A new type of wind generator could solve these problems: Vortex Bladeless has created a new design for wind turbines that it claims are cheaper to manufacture, bladeless and practically silent.
Bladeless turbines use a different technique taking advantage of vorticity, an aerodynamic phenomenon that creates “repeating pattern of swirling vortices”. This complicated-sounding principle is best understood by watching the famous collapse of the Tacoma Narrows Bridge in 1940.
Generally avoided in design, vorticity offers an opportunity to harness and transform wind into kinetic energy and then electricity.
Vortex Bladeless co-founder, David Suriol claims their creation is a leap forward in wind energy, and is a “more efficient, cost-effective, and environmentally friendly way to produce energy, reducing manufacturing costs by 53%, cut maintenance costs by 80%, and would represent a 40% reduction in both the carbon footprint and generation costs, when compared to conventional bladed wind turbines”.
The Vortex is also said to be quieter (than standard wind turbines), and to present a much lower risk to birds and the local environment.
According to an interview in Renewable Energy Magazine, the company has already raised over €1 million from both private and public funds in Europe, and is expected to roll out its pre-commercial prototype within the year, (to see more on Vortex Bladeless crowd funding see their website).
The shift from fossil fuels to renewable energy is being driven in part by the demand of consumer, including businesses. Cheaper, smaller and less disruptive wind turbines could help expand the impact of wind energy on future local and national power grids.
Businesses are now in an almost unique situation of being able to clearly compare energy and switch electricity supplier to one that reflects their ethical or economic priorities – or a mixture of both. Whether you want green power from 100% renewable generation, care more about cost than how your power is generated or want a low-carbon compromise, there is a supplier to suit.
The only barrier is time. It can take many hours to trawl through the scores of possible providers, speaking to each in turn.

Super helpful and easy to work with
"Recommend this company in a heartbeat - Nicole Borneuf was super easy to talk to, was not pushy in the slightest, very helpful and replied with all my questions very professionally and did all she could to help. I had to deal with a few companies to sort my business energy out, all but Nicole were too pushy for my liking and I refused to follow through with them. Thank Nicole - you are a credit to your company, thank you for making the stressful energy change so easy."This review was posted by Mia Drew on the 29th of March 2017
An Extremely Competent Company
"Switch my business has not only helped my SME secure a good energy deal for the second year running but Jessica swiftly found a alternative supplier for me when I was let down on the day of switching by the new contractual provider I had chosen some 4 months previously. Being suddenly out of contract and without provider is everyone's energy nightmare. Greatest thanks."This review was posted by S McMillan on the 29th of March 2017

Quick & Easy
"Kabibi was very helpful and the whole process was very efficient. The one small reservation I had was that I was phoned up by Kabibi almost immediately having received my online quote - which wasn't enough time for me to finish reading the quotes! Fortunately she was able to assist me in a greater savings on both Gas & Electricity, and so as long as the switchover is seamless I will remain very happy with the service."This review was posted by Amanda Brown on the 21st of March 2017
