This document discusses ecological buildings and sustainable energy sources. It asks the question of how buildings can be changed for future benefit. It then lists solar energy, hydro energy from dams and rivers, and wind energy from turbines as the three main sustainable energy sources. Several small questions are posed about ways to improve energy efficiency in homes through windows, insulation, and other design elements. Keywords covered include solar, wind, hydro, and eco-friendly design approaches for kitchens, bedrooms, and bathrooms.
