In a society that is growing ever more aware of its impact upon the environment, this is one of the many ever present questions people have.
Flagstaff is currently in an odd spot for renewable energy. Although it does receive sunlight, it is not consistent like in Phoenix. Also, no major rivers run close to Flagstaff. The terrain is also rough and uneven. However, this should not dissuade you from investing in renewable energy here in Flagstaff.
Solar power is the one of the three, and quite possibly the most well known, older faces of renewable energy. While Flagstaff, as previously mentioned, receives less sunlight than most of Arizona, it is still viable to invest in solar power. The upfront costs to installing a typical 5 kW system is made up in saved energy within 12 years. 18 years after that, a profit in $23,000 is made in saved energy. Even if the upfront costs to a solar system is too prohibitive, it is still entirely possible to buy small solar generators or solar lights.
Hydroelectric power is, unfortunately, not a very viable venture within Flagstaff. However, it is still possible to build microhydropower system and use that to generate electricity off of small streams.
One of the oldest sources of energy, wind power should be considered in Flagstaff. The city currently sits within a wind density zone that makes building large turbines a decent expenditure. If a Sky Stream 3.7 kWh wind turbine were to be build in Flagstaff, it would take only 7 to 11 years to recuperate the costs as opposed to the 12 years of solar energy. While smaller, home-based wind turbines are not quite as efficient in terms of energy production, they still should be considered. After all, the costs of building and installing one is not as prohibitive with systems costing as low as $3000. Even Northern Arizona University has a small wind turbine set up to power its renewable energy instruction laboratory.
So while Flagstaff may not seem to be an ideal location for renewable energy, it has the potential to be able to produce vast amounts of energy from renewable resources. So please, for the welfare of not just the Earth but for the welfare of the human race in general, take into consideration the possibility of power generation from renewable resources.
