It's not just ships zapping each other with lasers in the dark void of space; there's a caterpillar surface transport crawling over the rocky volcanic moonscape, a shoot - out with a fleet of flying saucers, a mind - controlled assassin sabotaging a human rocketship and of course the alien assault on Earth landmarks in the final battle.

Electrification will gradually deliver carbon - free surface transport, while solar power can produce both heat and cooling (and more electricity) at reasonable costs in the tropics and subtropical regions. (newstatesman.com)
Whether or not global warming is entirely or largely due to human use of carbon for fuel, the reduction of the dependence on carbon makes sense for reducing asthma in children; reducing black lung disease; reducing the production of coal ashes, residues, and effluents; reducing the impact of carbon greenhouse gasses; reducing pipeline failures; reducing coal and oil surface transport accidents; reducing pipeline - related warfare; and reducing air pollution.
