1. What is “green energy?”
According to Cambridge Dictionaries Online, green energy is “energy that can be produced in a way that protects the natural environment, for example by using wind, water, or the sun”. Solar energy is the conversion of the rays from the sun into a useful form of energy, such as heat or electricity. Solar energy when converted to thermal/heat energy can be used to both heat water and heat spaces in buildings and homes. Wind energy is another example of green energy. Wind power is the conversion of wind energy into a form of energy by means of wind turbines and windmills. Hydroelectricity refers to using hydro power, the power that comes from the energy of either falling or running water, to produce electricity. This is the most widely used form of green or renewable energy. Another example, geothermal energy, is a form of thermal energy that is generated in the earth. Hot springs are an example geothermal energy that has been used for bathing, space heating, and the generation of electricity. Ocean thermal energy uses the temperature difference between the warmer surface ocean water and cooler deep water to produce electricity.
2. What is “carbon footprint?”
According to Wikipedia, a carbon footprint is the amount of carbon dioxide that a person emits during their day to day activities. It measures the quantity of resources you use and how your actions contribute to the greenhouse gas emissions. These emissions are what
Ecological footprint helps us understand human pressure on the planet. It compares human demand with the planet Earth’s ecological capacity to regenerate it is important to change our lifestyles in order to lead a fulfilling life without degrading the environment.
Carbon footprint is the total of greenhouse gases produced by an individual’s habits as well as the energy required to produce things an individual consumes.
The ecological footprint quiz started off reviewing my eating habits. The first thing it asks is the country of residence. Then it reflects how often I ate certain meats and dairy related items. It checks to see the amount of fresh produce versus processed foods that you purchase. It also considers what material items you get, and how often you buy and replace them. It checks what kinds of residence you live in, whether you have electricity and running water, and how many people live with you. It also considers size of the home, materials of the building and any forms of renewable energy the home utilizes. In my case I don’t believe my household uses any forms of renewable energy. I know that our energy supplier is the Southern Maryland Electric Cooperative, and they claim nearly 10% of their energy comes from renewable sources, although the biggest majority is oil
Hydropower is a renewable resource that is clean, affordable and durable. This resource is clean due to the way you gather the energy from it. hydroelectric and coal-fired power plants produce electricity in a similar way. In both cases a power source is used to turn a propeller piece called a turbine, which then turns a metal shaft in an electric generator (the motor that produces electricity). A coal-fired power plant uses steam to turn the turbine blades; whereas a hydroelectric
5. Water energy (Hydroelectric power) plants use water in a different way, converting the energy in falling water into electricity by passing it through turbines. Fuel Extraction and Production – Water is a critical resource for the drilling and mining of natural gas, coal, oil, and uranium. Pros: 1. Green 2. Reliable. 3. Flexible Cons: 1. Droughts 2. Limited Reservoirs 3. Expensive

A carbon footprint is the carbon dioxide production we leave behind due to our daily life activities. The size of our carbon footprint depends on what people do daily, and can be caused either directly or indirectly. Thought it is impossible to not have a carbon footprint at all, we can still reduce the amount of carbon dioxide we produce everyday. (Source 1) One reason why our carbon footprint plays an important role in the world, is because we can raise awareness to how much damage and harm we are causing the Earth unintentionally.
Hydroelectric is a form of energy it is a renewable resource. Hydroelectricity is the most important and widely used renewable source of energy. Hydroelectric relies on water, which is clean and renewable energy source. Renewable energy comes from natural resources. Non-Renewable energy source includes coal, oil and natural gas. Water is renewable because water continually recycles itself. To harness energy from flowing water, the water must be controlled; a large reservoir is created, usually by damming a river to create an artificial lake or reservoir. Water is channeled through tunnels in the dam. The energy of water flowing through the dam causes the turbines to turn and make the
Renewable energy is energy that comes from any natural process and can be quickly regenerated. Some of the most common forms of clean energy include solar energy, wind energy, and hydroelectricity. These types of electricity are gathered through technology such as solar panels, wind turbines, and hydroelectric dams. Other types of renewable energy less known include geothermal energy, biomass energy, and energy collected from ocean (Renewable). Geothermal uses the Earth 's heat to generate energy while biomass use plants and other organic materials to make energy and fuels. Ocean energy can be derived from a multitude of areas. Energy can be gathered from the tides, the wind, and can also be gained from the
Carbon footprint is the measure of the amount of plant resources you use. The more your carbon footprint goes up, the more effect it has on the environment. Everyday people are doing actives that are producing greenhouse gas emissions. If one sees their greenhouse gas emission going up, that means that there will be an increase in climate change which will then lead to global warming. Your carbon footprint has a huge effect on not only you but also the environment, human life and wildlife. This is why your carbon foot is important, it has an effect on everything around you. Some people might not know the effects of carbon footprint, what contributes to your carbon
According to Wackernagel et al. (1999), “the ecological footprint assesses people's use of natural capital by comparing their resource consumption and waste production to the regenerative capacity of the earth” (p. 604). Overall, an ecological footprint analyzes the impact a community or person has on the environment by assessing their use of natural resources and production of waste; this assessment is compared to the regenerative capacity of the earth and expressed as the amount of natural resources (e.g. number of earths) required to sustain specific levels of consumption and waste production.
Support: Solar power has very little pollution, uses no greenhouse gases and is a renewable source.
But what is a carbon footprint? Basically, carbon footprints are defined as the total amount of greenhouse gasses that are produced when it comes to supporting human activities (and which are expressed in equivalent tons of carbon dioxide) (What is a carbon footprint?). Driving a car, heating one's house, even buying
Ecological footprint is the effect of human activities which is measure in terms of biologically productive land and water which is required to produce the goods produced the goods consumed and assimilate the wastes that are generated, it is essentially the amount of the environment which is necessary to produce the goods and services necessary to support a particular lifestyle. The indicator is an estimate of the amount of space on the earth that an individual uses in order to survive using the existing technology and resources on our planet.
Renewable resources are also known as alternative energy sources. Alternative Energy is any source of energy that can be renewed (Issit). Renewable Energies include hydrogen fuel, biomass fuel, hydropower, solar power, geothermic energy, and nuclear power. Hydrogen fuel is an amalgamation of hydrogen and oxygen which is used to produce electricity (Issit). Biomass fuel is made from materials which have already been used, such as compost, and can be used to generate electricity (Issit). Hydropower can be created through moving water or wind to generate electricity (Issit). Using sunlight to produce electricity is called solar power (Issit). Geothermic energy is energy made by the heat under the earth’s mantle (Issit). Nuclear power is
