Energy
In physics, energy is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.
Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed.
What is ENERGY?
SLIDE NO. : 3
Energy
Energy is a backbone of complete production activity. Energy is essential for all life and all processes that occur across the entire universe. On Earth, the sun is the ultimate source of all energy that is available and used by people, animals, plants, and microorganisms. This energy may come directly, such as in the form of photosynthesis, or indirectly, such as in the form of fossil fuels, which long ago trapped the energy of the sun that is released when burned.

Sources of Energy
Non-Renewable
Coal, Natural Gas, Oil, Nuclear Energy
Renewable
SOLAR ENERGY, WIND ENERGY, GEOTHERMAL ENERGY, HYDRO POWER, BIOENERGY
It is energy derived from natural sources that are replenished at a higher rate than they are consumed.
This source of energy comes from sources that will run out or will not be replenished in our lifetimes—or even in many, many lifetimes.

Types of Renewable Energy
Hydropower
Hydropower uses the energy of flowing water, typically from rivers or dams, to generate electricity.
It is one of the oldest renewable energy sources and contributes to a significant portion of the world's electricity production.
Wind Energy
Wind energy is generated by harnessing the kinetic energy of wind using wind turbines.
It is a clean and abundant source of energy with increasing global adoption for electricity generation.
SOLAR ENERGY
Solar energy harnesses the sun's radiation using photovoltaic cells or solar thermal systems.
It is a widely available and versatile renewable energy source used for electricity generation, heating, and powering various applications.
Geothermal
Geothermal energy utilizes the heat from the Earth's interior to generate electricity or for direct use in heating and cooling systems.
It is a reliable and consistent source of renewable energy with minimal environmental impact.

Non-Renewable Energy
NUCLEAR ENERGY
We use radioactive fuel such as the element Uranium to generate nuclear energy and they are not considered renewable as they are a finite material mined from the ground and can only be found in certain locations.
Natural gas
Natural gas is a gaseous non-renewable resource that is found below the earth’s crust but near crude oil deposits in the subsurface. Natural gas primarily consists of methane, but may also contain other forms of natural gas such as propane, ethane, and butane.
Coal
Coal is created by compressed organic matter, and it contains carbon and hydrocarbon matter. It is formed from plant-filled swamps that have been covered by sediments for millions of years. Coal is extracted by digging up the ground and taking out the coal solids for processing into energy.
Crude Oil
Crude oil, also referred to as petroleum oil, is the only non-renewable resource that is extracted in liquid form. It is found between the layers of the earth’s crust, or between the rocks, and it is retrieved by drilling a vertical well into the ground and ocean floor.

ENVIRONMENTAL IMPACT
1. Climate Change: Fossil fuel combustion releases greenhouse gases, primarily carbon dioxide (CO2), contributing to global warming and climate change.
2. Air Pollution: Emissions from fossil fuel combustion contain pollutants like sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter, leading to air pollution and associated health issues.
3. Water Contamination: Oil spills and leaks can contaminate water bodies, posing risks to aquatic ecosystems and drinking water supplies.Renewable energy sources are naturally occuring and abundant.
4. Radioactive Waste: Nuclear power generation produces radioactive waste which requires safe storage and disposal to prevent environmental contamination.

Need for Transition
1. Climate Crisis: The burning of fossil fuels is a major contributor to climate change, necessitating a shift towards renewable energy sources to reduce greenhouse gas emissions.
2. Resource Depletion: Non- renewable energy sources are finite and will eventually be exhausted. Diversifying the energy mix with renewables helps ensure.
3. Environmental Protection: Renewable energy sources have lower environmental impacts and offer cleaner alternatives to mitigate air and water pollution.
4. Technological Advancements: Rapid advancements in renewable energy technologies, such as solar, wind, and geothermal, have made them more affordable and efficient, making the transition increasingly feasible.
