The document discusses various forms of green technology including LEDs, Core M processors, solar energy, and electric cars. Green technology is defined as technology that is environmentally friendly, uses renewable resources, and conserves natural resources. LEDs and Core M processors consume less energy than traditional alternatives. Solar energy harnesses the sun's power through photovoltaic cells without producing pollution. Electric cars are powered by electric motors rather than fossil fuels, reducing emissions and global warming. Using these green technologies can help address environmental issues like pollution and global warming.

2. What is green technology
• It is a technology which is
environmentally friendly.
• Developed and used in such a way
so that it doesn’t disturb our
environment and conserves
natural resources.
• Uses renewable source and made
of environment friendly materials.
• It is also known as environmental
technology and green electronics

3. LED
• Light Emitting Diode(LED)
• Made of PN junction diode
• Consumes less power
• More efficient
• Made of silicon
• LED bulbs used as light source
• LED’s used in display

4. Core M processor
• New generation Intel processor
• Very small in size
• Consumes less energy
• Produces negligible heat
• No need to use cooling fans
• Provides high graphics
• Increases battery life in laptops

5. Solar energy
• Sun light is converted into electrical
energy by photovoltaic cells(solar
cells)
• Made of PN junction in reverse bias
• Renewable source of energy
• Doesn’t produce any pollutants
• Easy to generate
• Made of silicon

7. Electric cars
• Energy source is electrical energy
• Engine is made up of electrical motors
• Doesn’t use fossil fuels
• Doesn’t release any pollutants
• Saves money
• Light weight and compact design
• Provides faster acceleration
• Renewable energy can be used

9. Conclusion
• By using these devices we can
reduce some of the environmental
issues
• By using electric cars we can
reduce global warming which is a
serious issues now.
• By using solar energy we can
reduce the pollution created by
thermal and nuclear power plants
