Ancient way of converting biomass into energy is just to burn it for producing heat, as humans practiced it for thousands of years. Still this is the most common way for conversion of biomass into energy in United States and elsewhere also.
The heat generated from biomass can be used for heating, cooking, and industrial processes, or for producing electricity.
Using biomass for burning haves some problems regarding some energy waste and also some air pollution if it is not carefully controlled.
There are many causes that lead to Global warming, with each of the reasons contributing more to the increasing intensity of the climate change that has affected our planet.
The main cause of global warming is the increase rate of greenhouse gases present in the earth’s atmosphere. These gases cause the the greenhouse effect, which traps the heat present on the earth by reducing the level of solar rays that are able to escape from our atmosphere.
Although the greenhouse effect is extremely important to support life on earth, by keeping our atmosphere warm enough to support life, the addition of human activities contributing to the quantity of greenhouse gases has caused an artificial increase in the intensity of the greenhouse effect, which has made this great phenomena a bad effect. Thus greenhouse effect is not bad, it is the increase in the amount of greenhouse gases that are causing the harm.
