name three types of renewable energy sources that were mentioned in the slide
solar, wind, and hydro
what are some of the energys that the world uses
AC, computers, phones, anything that requires energy
what are some things we can do instead of using fossil fuel?
- use renewable energy like solar, wind, hydro, and geothermal power
- improve energy efficiency by building better appliances, homes, vehicles
- Invest in electric transport (buses, cars, bikes)
- Encourage governments and companies to support clean-energy programs
- as individuals, save energy by turning off lights, using public transit, and supporting, renewable-energy programs
how does fossil fuels affect the environment?
- burning fossil fuels in green houses can release harmful pollutions into the enviroment such as sulfer dioxide and nitrogen oxides
- fossil fuels are resposible for 75% of greenhouse gas emmisions
- these gases react with water vapor, oxygen, and other chemicals in the atmosphere to form sulfuric and nitric acids, causing acid rain
- acid rain then comes down and makes soils more acidic and less fertile for vegetation
- increases the acidity of lakes and rivers, which can kill fish and other aquatic creatues by disrupting their reproductive cycles and damaging their gills
how renewable energy be better for the environment?
-reduce pollution, decrease dependence on fossil fuels, and support a more sustainable future
Why is energy important?
it is important in order to access technology, and power basic necessities.
why is it important?
- to reduce greenhouse gas emissions
- to slow down climate change
- to protect air quality and public health
- to make sure we have long-term energy sources for the future
why is nuclear sources better than nonrenewable energy sources
- they also take up less space than other resources, allowing habitat preservation
what are the responsibilities of the energy industry
-producing
-distributing
-selling energy sources
name one positive effect of living in canada
- very convenient and efficent power source
- makes life easier in some ways
- makes life more comfortable
why is it important that we don't use up all the fossil fuel?
it takes millions of years to naturally form fossil fuel and we burn it extremely fast
What are some effects of nuclear energy?
- however, nuclear reactors create radioactive waste. Storing this waste safely is a major challenge, and there is a risk of radioactive leaks damaging water supplies, crops, and the environment.
- Additionally, major accidents can release more radiation in the nearby community, making the environment toxic for many years after
-water used for cooling gets returned to the bodies of water at a much higher temperature and kill aquatic species and cause migration
what are the energy industries that refer to all the industries?
the energy industry also refers to all the industries involved in fuel extraction, manufacturing, refining, and distribution.
name one negative effect of living in canada
- if energy is produced from fossil fuels, then fumes created as a result can cause major health issues if inhaled
- if energy is produced through renewable sources like wind and solar, it prevents those issues
-people who cant afford energy will have a harder time than people who can
why do we need to make changes?
fossil fuels, which release large amounts of greenhouse gases and harm the environment. this leads to climate change, causes air pollution, and negatively affects wildlife and human health.
how is hydro energy affecting the environment?
- dams flood large areas to create reservoirs, destroying forests, wildlife habitats, and farmland, and forcing the relocation of communities
- can disrupt river flow and temperature, affecting aquatic life
- Dams can block fish migration, such as salmon
Describe the use of any of the three renewable energies that was named
- Solar energy uses panels to capture sunlight and converts it into electricity, offering a lean and increasingly affordable power source. Wind energy relies on turbines that turn moving air into electricity. Providing renewable power both on land and offshore, hydro energy generates electricity from the movement of water, often through dams and flowing rivers, and is one of the most reliable forms of renewable energy.
what are some cleaner ways of producing energy?
cleaner ways of producing energy such as solar energy, wind and hydro, will reduce and prevent those issues, offering a cleaner and more efficient option
why can't our current approach not support us forever?
The fossil fuel that we have right now is decreasing extremely quickly, making it harder to access supplies; because of this, we need to shift towards a cleaner and more sustainable energy source.
what are some of the effects on the physical environent that was listed?
Fossil fuel
hydro
nuclear
