ABSTRACT
This chapter concentrates on making the supplies as green as possible. Energy suppliers now offer various so-called 'green tariffs' for the supply of renewable energy to their customers. The selling of so-called green power to customers is therefore an accounting, rather than a physical, transaction. Suppliers offering renewable electricity are effectively undertaking to procure the relevant proportion of their electricity sales from renewable sources. There is a strong body of opinion, and a logical case, that green electricity should be charged at a premium only if its production is genuinely incremental; in other words, additional to the level that has to be produced under existing statutory obligations. Electric vehicles can be treated as being totally sustainable in fuel terms if they wholly use renewable recharging facilities, such as solar carports.
