Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat
RENEWABLE ENERGY

Renewable energy replaces conventional fuels in four distinct areas:
electricity generation
hot water/space heating,
motor fuels,
rural (off-grid) energy services.

Radiant energy emitted by sun Originates with the thermonuclear fusion reactions
occurring in the sun.The Earth receives 174 petawatts (PW) of incoming
solar radiation (insolation) at the upper atmosphere. The total solar energy absorbed by Earth's atmosphere,
oceans and land masses is approximately 3,850,000 exajoules (EJ) per year.

Sunlight on the surface of earth is the radiation received from sun.
India has adequate sunshine available for most parts of the year, including rural areas.
The amount of solar energy impacting the surface of earth is 1000 watts per square meter, which is about 32.8 million MW every second on the Indian land mass.
A large part of the incident heat is reflected to the outer space or radiated back to space.
India Has A Lot of Sun Light

A solar vehicle is an electric vehicle powered completely or significantly by direct solar energy.
It uses photovoltaic (PV) cells contained in solar panels convert the sun's energy directly into electric energy.

In 2010, the PlanetSolar, a 30 metre long, 15.2 metre wide catamaran yacht powered by 470 square metres of solar panels, was unveiled.
It is set to circumnavigate the Earth and is so far the largest solar-powered boat ever built.

From 1970 many experimental projects were launched- Sunrise- 1973 Solar Riser- 1979 Solar Challenger- 1981 and NASA Projects (NASA Environmental Research
Aircraft and Sensor Technology) like HELIOS & CENTURION.

AdvantagesAll chemical and radioactive polluting byproducts of the
thermonuclear reactions remain behind on the sun, while only pure radiant energy reaches the Earth.
Energy reaching the earth is incredible. By one calculation, 30 days of sunshine striking the Earth have the energy equivalent of the total of all the planet’s fossil fuels, both used and unused!
DisadvantagesSun does not shine consistently.Solar energy is a diffuse source. To harness it, we must
concentrate it into an amount and form that we can use, such as heat and electricity.
Addressed by approaching the problem through: 1) collection, 2) conversion, 3) storage
Advantages and Disadvantages
![Page 25: Renewable energy](https://reader036.vdocuments.net/reader036/viewer/2022062319/557dda37d8b42a4e358b46d3/html5/thumbnails/25.jpg)
Argument that sun provides power only during the day is countered by the fact that 70% of energy demand is during daytime hours. At night, traditional methods can be used to generate the electricity.
Goal is to decrease our dependence on fossil fuels. Currently, 75% of our electrical power is generated
by coal-burning and nuclear power plants.Reduce the effects of acid rain, carbon dioxide, and
other impacts of burning coal and counters risks associated with nuclear energy.
pollution free, indefinitely sustainable

WASTE: Waste (also known as rubbish, trash, refuse,
garbage, junk, litter, and ort) is unwanted or useless materials.
In biology, waste is any of the many unwanted substances or toxins that are expelled from living organisms, metabolic waste; such as urea and sweat.

Hazardous wastesSubstances unsafe to use commercially, industrially,
agriculturally, or economically and have any of the following properties- ignitability, reactivity & toxicity.
Non-hazardous Substances safe to use commercially, industrially,
agriculturally, or economically and do not have any of those properties mentioned above.
These substances usually create disposal problems.

Plastic recycling is the process of recovering scrap or waste plastic and reprocessing the material into useful products, sometimes completely different in form from their original state.
Plastics are also recycled during the manufacturing process of plastic goods such as polyethylene film and bags.
