The document discusses energy and climate change. It defines energy and different types of energy sources, distinguishing between non-renewable sources like fossil fuels and renewable sources like solar, hydropower, and wind. It then defines climate and climate change, listing some of the main causes of climate change like greenhouse gases. The document outlines several indicators of climate change and impacts, such as rising sea levels, increasing temperatures, extreme weather events, and effects on ecosystems and human society.
2. • Energy
Energy is the quantitative property that is transferred to a body or a
physical system, recognized in the performance of work.
• The law of conservation of
energy
3. Types of Energy
Non-renewable energy: Non replenish (fossil fuels, nuclear energy,
etc)
Renewable energy: Replenish (Solar, Hydropower, wind, Biomass,
etc)
Non-renewable
energy
Renewable

4. Non-renewable energy [Fossil Fuels]
Buried Plant & Organism and making Fossil
fuels
Mining Fossil Fuels and
Coal, Oil, Natural Gas, Nuclear
energy, etc.

7. Climate
Climate is the long-term weather pattern in an area, typically
averaged over 30 years.
Climate Change
When temperature and weather pattern is shifted then it is
known as climate change also global change.
8. Cause of Climate Change
Heat-trapping Greenhouse Gases.
Reflectivity or Absorption of the Sun's Energy.
Changes in the Earth's Orbit and Rotation.
Variations in Solar Activity.
Changes in the Earth's Reflectivity.
Volcanic Activity.
9. Climate Change Indicator
Global warming
Changes in polar and glacial ice
Rising sea level and ocean acidity
Changing wind and weather patterns
Health and society
Changing ecosystem
