I am in the process of creating a wildlife garden pond. Rough dimensions are 60ftx30ft with average depth of 4ft. I want to be as enviromentally friendly as possible and would like to avoid additional energy use (electricity for pump for water circulation and filtering). Is it possible to do this without the water becomming stagnant and preventing the growth of algae – could bales of straw do the trick? Are there any other ways I could deal with with water circulation such as tap water from well or rainwater diverted from roof? Any advice appreciated.

It is very easy to divert roof water into a pond and it will help to keep it fresh. There is no need for pumps etc Top up the pond if it gets very low in level. Normally a roof-replenished pond will not drop by more than about 10cm in level in a normal summer.
The roof will provide too much water occasionally and an overflow might be needed, or simply allow the pond to overflow its banks. The water seeps away to surrounding soil.
