Hello and heres my logo for your contest. It features a tribal styled sun, In the sun theres a solar panel represented by the diamond and linear pattern. It features a bright patch effect on the sun to represent light and also shadow etc to show dark and to give the overall effects of the sun. The colours I used were tones of green and yellow, the yellow to represent the sun and the green to represent energy and the effect the sun has on the growth of nature and also the green which a solar panel contributes towards saving the environment. If you like my entry I would be happy to experiment more with colours and writing etc just drop me a comment.
Yours John
