Nasser Al-Khater, the organising committee's communications and marketing director, also said the tiny gulf state would construct its stadiums with modular technology so it could downscale them after the tournament, and donate seating to countries with little sports infrastructure.
Al-Khater said the wealthy emirate already boasted the world's first cooled stadium, albeit with traditional energy sources. Temperatures in Qatar can reach more than 40 degrees Celsius in the summer months.
"We showed [world governing body] FIFA how the cooling technology works, it was warm outside but in stadium was cold they wanted their jackets," Al-Khater said during a trip to Berlin for a Qatari business and investment conference.
"So cooling a stadium is not the issue."
"When you don't use it for the stadiums you feed it into the grid," he said.
"With solar, the big challenge is how do you deal with solar technology in the desert in terms of withstanding the elements and getting it clean so it is efficient," Al-Khater said.
Historically, the World Cup has always been held in June and July and any change could lead to a major scheduling headache with the major European leagues normally playing through the winter. Qatar's right to stage the 2022 World Cup if the event is moved to the winter months would also be open to a legal challenge.
"Whether it is a winter or summer World Cup we will be ready," he said.
Al-Khater said Qatar, a tiny country home to just 1.7 million inhabitants, was using modular seating for the upper tiers of its new stadiums in order to be able to downsize after the World Cup. "The idea is we will contribute the seats to countries that need to develop their sporting infrastructure."
"One thing we want people to know is alcohol is not part of our culture," he said. "And every World Cup you go to, people experience the local culture, its differences and similarities."
