Public services can be hit hard if local authorities do not act quickly when it comes to energy efficiency, especially since securing the necessary funding is not a very difficult task nowadays — there are a number of financial products and investment vehicles that local authorities can tap into to provide the upfront capital for large-scale energy efficiency projects. What's more, with technologies as efficient as LED lighting, these projects can actually generate revenue as the savings go beyond the level of self-funding, freeing up capital to spend elsewhere.
