it still gives a lot of money if you get some % uppers (im at 22% bonus)

:/ they cost alot though if have to buy all that whit rocketfuel

No, Decorations cost the ¢ money:



The +% gets added to all towers (energy included) through-out your world
only a few cost rocket fuel

Is there an auto collect for your home? If not I think one should be added simply because it's annoying to have to collect every minute ^^

Nope, Not sure if one is going to be added because it is supposed to be a "treat" and in my opinion is more of a built in safe to make sure you never go broke or cant do anything because you don't have energy or money

The collect all feature is nice, except that I don't have the energy capacity so much of it goes to waste. Separating it into two functions would be nice. One as collect all from buildings, and one as collect all energy. I end up not using it at all anymore because I can't repair everything if I do.

Okay thanks for the info

Depends on your level, when you are below 11, your capacity is low, but when you get to level 11 16 21 26 31 36 ect.ect. up to 60, you get massive bonuses to your capacity
If you are worried about that you could go about different strategies.
When I was level 15, I had 3 entire squares covered in 1x1 energy boosters, and a bunch of massive energy gainers.
When everything is ready, use the big energy producers and clear some large garbage or midsized and then use the collect all
Sometimes a little waste is needed to produce quicker results, just like real life

When are the contests ending?

Also good to note any excess energy beyond your cap is not wasted when you collect it. It is actually sold back to GreenSpace Corp. at a rate of 1 credit per 1 energy
