Renewable energy
This document discusses various sources of renewable energy including fossil fuels, solar energy, geothermal energy, hydro energy, and hydrogen as a potential future fuel. It notes that while fossil fuels currently provide a reliable energy supply, they are non-renewable and cause environmental issues like pollution and global warming. Renewable sources like solar, geothermal, and hydro provide clean energy alternatives, but technologies are not yet mature and established. Hydrogen is highlighted as an ideal future fuel because it is abundant, non-toxic, and can be produced from renewable resources, though safe storage and transportation of hydrogen remains a challenge.
alternative sources of energy
The document discusses the need for alternative energy sources due to the finite and unsustainable nature of fossil fuels. It then outlines various alternative energy sources including solar, wind, geothermal, and tidal energies. For each type of alternative energy, it provides brief descriptions of the technology and how it works to generate energy. Overall benefits of alternative renewable energies are also highlighted such as being sustainable and producing minimal environmental impact and pollution.
Renewable resources
This document discusses three types of renewable resources: biomass, nuclear energy, and geothermal energy. Biomass acts as a natural battery that stores solar energy as long as it is produced sustainably. Nuclear energy is derived from nuclear fission reactions that split atoms to produce heat and boil water to generate electricity. Geothermal energy uses steam from reservoirs of hot water deep underground to power turbines that generate electricity without fossil fuels.
RENEWABLE AND NON RENEWABLE RESOURCES
Renewable and non-renewable resources are classified based on their ability to regenerate. Renewable resources like solar, wind and hydro power can be replenished naturally, do not pollute, and are available in many locations. However, they can be inconsistent. Non-renewable resources like coal, oil and natural gas were created over millions of years and produce greenhouse gases when burned; once depleted they cannot be replaced. Conservation efforts aim to reduce consumption and waste of all natural resources.
Non renewable-energy
Non-renewable energy resources such as fossil fuels are finite and will be depleted within 50-60 years. They include coal, petroleum, and natural gas, which were formed from the remains of dead plants and animals over millions of years. While reliable sources of electricity, their use also produces greenhouse gases and other pollutants that harm the environment and health. Nuclear energy generates power through nuclear fission or fusion, but poses challenges of nuclear waste storage and safety. Both non-renewable and nuclear energy have benefits as well as drawbacks to consider regarding sustainability and environmental protection.
Resources [renewable and non renewable]
There are two types of resources: non-renewable and renewable. Non-renewable resources like coal, petroleum, natural gas and uranium are fossil fuels and minerals that were formed over millions of years and cannot be replenished on a human timescale. Renewable resources like solar, wind, hydroelectric, geothermal and biomass can be replenished naturally or through human efforts within a short period of time and do not get depleted. While non-renewable resources are finite, renewable resources are generally more sustainable as they are constantly replenished.
Energy resources and basis
Energy comes from various sources both renewable and non-renewable. The five fundamental sources of energy are nuclear fusion in the sun, gravity from the Earth and moon, nuclear fission reactions, energy in the Earth's interior, and energy stored in chemical bonds. Non-renewable sources include fossil fuels like coal, crude oil, and natural gas obtained from ancient organic matter underground. Nuclear energy also comes from mining and refining uranium. Renewable sources are solar, wind, hydroelectric, geothermal, and biomass which use ongoing natural processes and can be replenished unlike non-renewable sources. Renewables are better for the environment but make up a smaller share of current energy usage.

- 2. VOCABULARY • Advantage: a condition or circumstance that puts one in a favorable or superior position. • Disadvantage: place in an unfavorable position in relation to someone or something else • Renewable: a source of energy that is not depleted by use, such as water, wind, or solar power. • Non-renewable: a nonrenewable energy source. • Biomass: organic matter used as a fuel, especially in a power station for the generation of electricity. • Hydro Power: or water power is power derived from the energy of falling water or running water, which may be harnessed for useful purposes. • Geothermal Energy: is the heat from the Earth. It's clean and sustainable. • Solar Power: power obtained by harnessing the energy of the sun's rays
- 3. VOCABULARY • Wind Power: power obtained by harnessing the energy of the wind. • Coal: is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. • Gas: flammable gas, consisting largely of methane and other hydrocarbons, occurring naturally underground (often in association with petroleum) and used as fuel. • Nuclear Power: electric or motive power generated by a nuclear reactor. • Oil: a viscous liquid derived from petroleum, especially for use as a fuel or lubricant • Consumption: the act of consuming, as by use, decay, or destruction. • Production: the action of making or manufacturing from components or raw materials, or the process of being so manufactured.

- 5. RENEWABLE
- 7. PROS OF RENEWABLE • Renewable sources of energy are renewable and easily regenerated. This is unlike fossil fuels which are perishable once used. • Renewable source of energy such as solar produce clean energy that does not pollute the environment. This is because no burning is required during usage of the energy. • Most importantly, renewable energy are available everywhere throughout the world thus there is no chance of the sources becoming depleted in future. For example, solar energy is everywhere as the sun will always be there every day. • Maintenance cost needed to install and use the renewable energy is relatively cheap. Solar energy can be trapped easily and used for domestic needs. • Renewable sources of energy boost economic growth and increase job opportunities. This includes electrical energy which is used to run many industries.
- 8. CONS OF RENEWABLE • Difficult to produce the energy quantity that is equivalent to that produced by nonrenewable fuels • Technology required to trap renewable energy is costly. Setting of dams requires high initial capital to construct and maintain • Most renewable sources of energy are affected by weather thus reducing their reliability. For example, hydro generators need constant rainfall that will overflow the dams, wind turbines only rotate if there is wind of a given speed.
- 9. PROS OF NON-RENEWABLE • Most nonrenewable sources of energy are easy to transport from one area to another. For example petroleum oils which can be transported via pipes. • Cost of producing nonrenewable energy is low since they are naturally available. Furthermore they are cheap to transform from one form of energy to another. • Most of this energy sources are abundantly available in different areas. Their availability is not affected by climatic condition.
- 10. CONS OF NON-RENEWABLE • Produce harmful green house gases which contribute global warming. Coal once burnt produces carbon dioxide harmful to the environment. • Once they are depleted they cannot be replaced making them expensive to obtain.
- 11. WHAT HAPPENS WHEN NON-RENEWABLE IS GONE? • Fossil fuels (non-renewable) will not last forever or will it? • Get in groups per teacher instructions • You will have 2 minutes to discuss what you think about non- renewable vs renewable and which one you think is better and why. • In your journals write down your thoughts on the energy sources and what you think will happen over the next 10 years.
