Document Summary
Largest tidal range in the world 16m. One of 3 tidal energy plants in world. Thinking about new tech in a new way. Still only supply little of our power but growing exponentially. Funding for renewable energy was extremely low in canada: now increasing. Solar energy has been used for hundreds of years. Passive solar energy: most common way. Active solar: tech to focus, move, or store solar energy. Maximize absorption of sunlight in winter, keep cool in summer. Thermal mass: construction materials that absorb, store and slowly release heat. Passive solar methods conserve energy and reduce costs. Specific tech for capturing, moving, storing energy. Net metering: sell excess electricity to local power utility. Components must be mined: hazardous substances. Could meet 15% of nation"s electrical needs. Taller is better: minimize turbulence, maximize wind speed. Offshore is better: higher wind speeds, most promising. Use less water than conventional power plants.
