By definition "Sustainability" is ultimately characterised by way of a system which requires no subsidy in the long term. However,Photovoltaic as well as other forms of Green energy sources will still require a heavily subsidised system set up for a length of time to permit it to develop in a protected environment and take roots to be able to ultimately have the opportunity of competing against fossil fuels and the nuclear power which right now we rely so heavily upon. But for just how long will this support be needed? I don’t think that anybody who actively entered into or enters the business either as an investor, customer, company owner or installer thought that the initial subsidies were sustainable or indeed healthy for the industry over time but without them the industry would not be where it is today! However, many individuals built their UK business models around subsidy guidelines comprising the feed in tariff system that has been changed radically by government and caused many organizations to go bust and made unemployed lots of the workers who had been drawn into the industry. This is all fact! After reviewing the Energy industry as a whole, the Economy and ways in which best to integrate Renewable kinds of generation into the domain for the greater good of all i created the design for a system which will result in “Grid Cost Parity” for renewables and that will not require a subsidy system to work. In a nutshell, The conceptual background to the current patent application is founded on the benefits belonging to the practice of sharecropping by communities on a collective basis embedded within a competitive marketplace by directly attaching the rights and distribution to the output of the crop (In this case Sustainable energy Electricity, farmed on a large scale basis) directly back to the owning individuals within defined limits for his / her own personal useage and therefore outside the monetary and taxation system. This financial approach being in line with all the Governments current policy with regards to the benefits obtainable from the current feed in tarrif system for domestic installations. For those who are truly an enthusiast of finding and supporting a way to make the world a significantly better place then please visit my website http://www.solar-panel-installs.com and follow the tab to the Patent Application which has all the details of the design that is now at the publication stage with the Intellectual Property Office in the UK.Please be aware that the application is only for the UK and the design can be used as the cornerstone for any project outside of the UK on an open source basis. More information on this application along with other articles which i've written about the subject, including “Why and How the Government and the Energy Companies Sacrificed thousands of Jobs in the Solar PV Industry” are also open for discussion on my Solar blog page. I truly believe the best way forward is to keep installing although the Green deal is actually just another load of Green Spin Policy.
