The body needs a way to get oxygen in and carbon dioxide out, which is through diffusion. When blood returns to your lungs from the body, it has a lot of carbon dioxide and no oxygen. The carbon dioxide concentration is much greater in your blood than the alveoli.
What Will a 10,000 Watt (10 kW) Solar System Cost in Your State in 2017? 10kW solar systems are among the most popular solar energy system sizes in the country, producing enough electricity to power a home with slightly above-average electricity consumption.
Average system costs = $95 per square foot. Average solar panel output = 10.6 watts per square foot. Average solar energy system costs = $8.95 per watt. In order to compare the solar energy costs to conventional hydrocarbon fuels, we must covert the $8.95 per into KWH.Letâs make two calculations to measure the total electric energy output over the lifespan of the solar energy system.verage solar energy system costs = $8.95 per watt.
