global energy consumption and it's effects

global warming is here and there are things that we can do. it seems in the United States and all over the world for that matter, ( since the world's total energy consumption per capita is up 43 kgoe (kilograms of oil equivalent per person) in the last three years) that we prefer houses and space that are expensive, elaborate and high in energy. I think that houses and structures could be better by demonstrating how many and how much natural resources it can save, generate, or collect. I have been focusing on the environment lately, thinking of a concrete component that betters the environment was challenging but i think i am getting the hang of it. there is scientific evidence to support the fact that natural sunlight is the key element in photosynthesis and plants can not live without photosynthesizing. plants are the answer in our struggle with global warming. but how do we get natural sunlight to places where there are no windows?
