Nah, they are good, and use less electricity and water than hand washing. A lot of people use the sink method thinking they're being green, but it's the opposite.
Most dishwashers get heavy food off plates now, but the majority of dishes don't even have that, and if you took away my dishwasher I would kill you.
The same study suggests one method of manual washing that beats dishwashers: the two basins methods (you fill one sink, plugged, with hot water, scrub the dishes inside that sink without running water, move the scrubbed dishes to a second plugged sink filled with cold water to rinse them).
Finally, that study bases its estimates on the U.S. national average electrical grid carbon intensity, and assumes water is heated in the home through natural gas; and most of the energy consumed is for water heating. So if you're living in, say, France (where 90% of your energy comes from low-carbon sources such as nuclear or hydro-electric dams), and your water heater is electric, the results might well be different.
Modern dishwashers don't need a pre rinse though. Just clean the filter after every few washes, takes like 5 minutes. My dishwasher has saved me a ton on the water bill and paid itself back many times. Not American btw.
That's because most Americans just don't fill the soap slot. So their dishwasher doesn't work properly, which they assume is because they are supposed to be like that. If you actually fill the soap slot like you are supposed to, you can leave crusty old stuff on your dishes and it will still come off most of the time.
Dish washers are another scam thing every American has. They basically wash all their dishes by hand, then wash them again in the machine.

Also a big factor.
I just got a dishwasher again after not having one in my places for the last.... 8 years?
It's great.

Apparently, dishwashers beat usual methods of handwashing even when the environmental production cost of the dishwasher is taken into account (though that estimate doesn't seem to include the cost of transporting the appliance, mind you).

Costs more as in, financially - still hurts the environment less.

Wait, dishwashers have a filter?
Mine does at the bottom. It's like a little cylinder basket shaped thing

What do you mean? They just fill the dishwasher with dishes, and turn it on? No soap?
They usually just toss in a detergent packet, no soap or rinse aid.
Mostly about the reflexive need to super-sanitize everything. It's only really useful for glassware.

You really shouldn't need to prerinse, this video is a pretty good explanation of while they can suck.
