Despite conflicting political messages in the USA, its military are investing heavily in renewables:

Renewable energy: saves money, energy, reduces carbon footprint
The UK is also going to have to invest seriously in its building and infrastructure:
Climate change: and rendering property obsolete
Exeter’s hospital is doing just that, according to Radio Exe:
RD&E to invest in sustainable energy
It could reduce costs by £800,000 a year.
The Royal Devon and Exeter NHS Foundation Trust (RD&E) is investing £7 million in sustainable energy measures. The project will see state-of-the-art energy technology installed at five sites across Exeter, helping the RD&E to cut its energy costs by 17 per cent.
Design and construction is set to be completed by the end of April next year (2020) It includes the installation of a new 1.5MW combined heat and power unit that will generate power onsite at Wonford Hospital, as well as roof mounted solar panels at Wonford and Heavitree Hospitals and Mardon Neuro-Rehabilitation Centre in Exeter. Wonford and Heavitree Hospitals will also benefit from new LED light fittings and improvements to the air conditioning systems, while Mardon Neuro-Rehabilitation Centre will profit from the installation of new energy-efficient boilers.
Once complete, it will reduce annual emissions by more than 2,200 tonnes of carbon dioxide – the equivalent to taking more than 1,450 cars off the road. The work is part of the RD&E’s wider sustainability programme to help it lower energy costs and become a greener organisation with a smaller carbon footprint.
