advantages
1. it is a free gift of nature. we can get renewable energy from the sun , water and wind
2. It would result in more decentralized and energy-efficient national economies
3. it is not subject to supply cutoffs and natural disasters
4. Improve economic and national security for developed, developing and underdeveloped countries of the world
5. Reduction in air and water pollution
Factors holding back this transition:
1. Government tax breaks, subsidies, and funding for research and development of renewable energy resources is minimal compared with nuclear power production and traditional; fossil fuel production.
2. It is a risky investment for companies to invest in renewable energy because of the taxation on them by the Government is on the increase
3. Prices we pay for nonrenewable fossil fuels and nuclear power don't include the harmful environmental and human health costs of producing them.
Distinguish between a passive solar heating system and an active solar heating system
passive solar heating system absorb and store heat from the sun directly within a well-insulated structure.
Active solar heating systems is when energy is collected from the sun by pumping injectores like fluid. usually mounted on a roof or on special racks to face the sun. heat from the sun is stored through this means in a container.
The major advantages and disadvantages of such systems for heating buildings.
.1 Very low emissions of CO2 and other harmful gases
2. Very low land disturbance
3 Not too expensive (passive)
1.Need access to sun 60% of time during daylight
2. Sun can be blocked by structures
3. costs intensive in terms of installation and maintenance for active systems
4. backup system is expedient for cloudy days
