It isn't possible to determine the entire effect of an element of human culture without knowing the full reach or what substitutes might arise.
Well, you'd have to define religion.
Organized beliefs?
Faith in a "higher power" of some kind?
Without attributing to a deity or something, people still have ideals and beliefs that would take the place of religion as far as lobbying and wars and such. People don't join a religion unless they buy it or generally agree, so even if they didn't ascribe their morals or values to a "higher power", they'd still unite anyway.
Faith in a "higher power". People like to think that religion has suppressed science because they deemed it an attempt to undermine their "god". Well, how many scientific things were suppressed by a religion, really? Yeah, there's the whole "age of the earth" and "evolution", but how recent is that and how much did it relatively suffer? Not a lot of science has really been relevant to religion, so they haven't gotten involved. Even under an oppressive theocracy, people who disagree have still studied what they wanted, they just didn't let the government/religious leaders know about it.
While on science, the morality issue is still existent without religion, there are non-religious people are uncomfortable with the idea chopping up unborn babies for stem cell research. Also politically, some people, without religion, don't like the idea of homosexual marriage or abortion.
Religion has also motivated a lot of "good", social service organizations, mission work, etc. Again, this is just shared belief in helping other people, so they would probably exist the same.
Hope and such... well, there is a certain motivation in religion, especially in the afterlife, and something to strive for (or avoid). Of course, without religious afterlife, people might be more motivated to do more with the life they are given, and determine how to make it longer.
In short, not that different.
