Q. How much radiation is in the atmosphere?
Background dose rate examples
| Radiation source | World | US |
|---|---|---|
| Inhalation of air | 1.26 | 2.28 |
| Ingestion of food & water | 0.29 | 0.28 |
| Terrestrial radiation from ground | 0.48 | 0.21 |
| Cosmic radiation from space | 0.39 | 0.33 |
Q. How does sun radiation affect climate?
The Sun’s rays warm our world, stir air and ocean currents, and catalyze chemical reactions in the atmosphere. The Sun-warmed surface evaporates water to form rainclouds that redistribute fresh water around the world.
Q. Why is coal so cheap?
Coal is only considered cheap because coal plants do not have to pay for the full social and environmental costs of coal burning on people’s health, the natural environment, and our climate.
Q. Is renewable energy a good investment?
Renewable energy companies that generate free cash flow and have strong balance sheets have a competitive advantage over financially weaker rivals, since they have greater access to the capital needed to finance growth. That’s why investors should focus their attention on financially strong clean energy companies.
Q. What is the cheapest way to produce electricity?
