Shaping North Ayrshire process
All new buildings should have solar panels. Development of small wind turbines where possible. Publicity to encourage homeowners to switch to renewable energy supply.
This feels like the wrong question to ask. These changes are both well documented and minuscule in relation to co2 production.
Never the less every single house, school and council building should have a green roof, solar panels & wind turbine. Every person should change electricity supplier to a properly green alternative. Every website for the council should be hosted on green, wind powered servers. Every product in your house should be obtained by an ethical supplier who has considered their own environmental impact.
I've already stated in previous answers - start with planning - you wouldn't build a house without a plan so you won't get a solution without a plan either.
Encourage community owned renewable energy production. Use this to power local homes and businesses, electric vehicles used for public transport and a network of charging points to encourage electric cars for private use. All public buildings / council houses should have solar panels fitted - feeding into the national grid.
Use the roadsides where suitable to plant materials which can be used for biomass fuel - absorbing carbon and providing energy. Roadside maintenance would be carried out by the energy company instead of the authority - reducing costs.
