I like the way the T gets close to the O in #192. And the symbol is good looking in #197, #191, #188. I don't want it to be very obvious- it is clearly a green leaf over a drop of crude oil in #192. I would like seeing some variations on that symbol, but more abstract. It should convey growing green that replaces oil, but without being obvious. I hope you can submit some more. Have fun. Thanks.
And I like the all caps with the "P" that extends below. But I don't love the curl of the P. I know it's in my number 1 ranking right now, but I prefer the P found in designs such as #126, #129. Those have a flatter part where the P connects to itself.
