The document discusses renewable energy sources such as solar, wind, and our idea for a portable wind turbine battery charger. It introduces renewable energy as sources that can be repeatedly used, like solar, wind, and hydro, without producing greenhouse gases. Solar energy is described as a clean source that can provide remote areas with power, while wind energy harnesses the kinetic energy of wind through turbines to generate electricity without emissions. Our idea is then presented as a compact, portable wind turbine to charge batteries for situations when people forget to charge devices or are in a rush. Solutions for sustainable energy are also listed, such as improving efficiency, increasing local renewable resources, finding transitional resources, and educating the public.

3. Introduction
Renewable energy refers to energy sources that are obtained naturally and
can be used repeatedly, such as solar, wind, hydropower, and geothermal.
These energy sources are considered renewable because they do not get
empty after usage unlike non-renewable resources and produce little to no
greenhouse gas emissions,
unlike non-renewable sources such as coal and oil.
The use of renewable energy is monitored and it created a great climate
change and achieved energy sustainability.

4. Solar energy
• Solar energy is a clean and renewable source of energy and does not
produce greenhouse gas emissions or other pollutants.
• Additionally, it has the potential to provide energy to remote locations
without access to traditional power sources,
• making it a key component of a sustainable energy future.

5. Wind energy
• Wind energy refers to the process of generating electricity using wind
turbines,
• which converts the kinetic energy of wind into electrical energy. Wind
energy is a clean and renewable source of energy that does not
produce greenhouse gas emissions or other harmful pollutants.
• by making it a promising alternative to fossil fuels. The efficiency of
wind energy generation depends on various factors, including wind
speed,
• the location of the wind turbines, and the design of the turbines
themselves.

6. Our idea
• We would like to present the idea that can recharge the battery by using wind
energy.
• In our idea a turbine that rotates by using the wind to produce electricity.
• This project is very compact to use so there are no transportation issues many
peoples tells that this project is like a windmill but it this easy to use and easy to
transport.
• Nowadays we are using many gadgets that are rechargeable but sometimes people
forgot or are in rush, they don’t recharge their batteries for that situation this project
is helpful

7. Solutions for sustainable energy
• Improve energy efficiency
• Increase local availability of renewable energy resources
• Find transitional resources (natural gas, nuclear)
• Government must promote R&D for alternative renewable energy resources.
• Educate the public
• All energy resources should compete in an open, free-market with NO government
control!
• The government needs to implement constructive subsidies not destructive subsidies
to promote change, this will lead to the conservation of resources and less over-
consumption.
