1. Solar Energy
Solar power harvests the energy of the sun through using collector panels to create conditions that can then be turned into a kind of power. Solar panel fields are often used in desert. The issue with solar is that while there is plentiful amounts of sunavailable, only certain geographical ranges of the world get enough of the directpower of the sun for long enough to generate usable power from this source.
2. Wind Energy
By using large turbines to take available wind as the power to turn, the turbine can then turn a generator to produce electricity
3. Geothermal Energy
Geothermal energy is the energy that is produced from beneath the earth. It is clean, sustainable and environment friendly. Hot rocks present below the earth heats up the water that produces steam
4. Hydrogen Energy
Water contains two-thirds of hydrogen and can be found in combination with other elements. Once it is separated, it can be used as a fuel for generating electricity. It is completely renewable
Wave energy is produced from the waves that are produced in the oceans. Wave energy is renewable, environment friendly and causes no harm to atmosphere. Producing wave energy can damage marine ecosystem
Wave energy is produced from the waves that are produced in the oceans. Wave energy is renewable, environment friendly and causes no harm to atmosphere. Producing wave energy can damage marine ecosistema. The problem is with the aging of the dams
It’s produced from organic material. Chlorophyll captures the sun’s energy by converting carbon dioxide from the air and water from the ground into
carbohydrates through the process of photosynthesis
one of the major renewable sources of energy available to the world. The energy is created through a specific nuclear reaction, which is then collected and used to power generators.
9-Fossil Fuels (Coal, Oil and Natural Gas)
They provide the power for most of the world, primarily using coal and oil. Oil is converted into many products, the most used of which is gasoline. Natural gas is starting to become more common.The issue with fossil fuels is twofold
Pollution: Pollution occurs when pollutants contaminate the natural surroundings; which brings about changes that affect our normal lifestyles. Consequence waste of
Types of pollution:
-Air Pollutionis the most prominent and dangerous form of pollution. It occurs due to many reasons. Effects: Respiratory and heart problems, global warming, acid Rain. effect on Wildlife, depletion of Ozone layer.
Solutions:Use public mode of transportation, conserve energy, understand the concept of Reduce, Reuse and Recycle Emphasis on clean energy resources, Use energy efficient devices:
-Water Pollutioncause an imbalance in the water leading to its severe
contamination and death of aquatic species. Water pollution not only harms the aquatic beings but it also contaminates the entire food chain affecting humans
-Soil pollution occurs due to human activities. Use of insecticides and pesticides absorbs the nitrogen compounds from the soil making it unfit for plants to derive nutrition from.
-Noise pollution is when an unpleasant sound affects our ears and leads to
psychological problems like stress, hypertension, hearing impairment, etc. Effects:
Hearing Problems, Health Issues, Trouble Communicating, Effect on Wildlife
-Radioactive pollutionIt can occur due to nuclear plant malfunctions, improper nuclear waste disposal, accidents, etc. Can sterilise soil and affect air and water.
-Thermal/heat pollutionis due to the excess heat in the environment creating unwanted changes over long time periods.Deforestation and air pollution.
Decrease in DO (Dissolved Oxygen) Levels, Increase in Toxins, Loss of Biodiversity, Ecological Impact, migration
-Light pollution occurs due to prominent excess illumination of an area. It is largely visible in big cities, on advertising boards and billboards, in sports or entertainment events at the night. Effects on animals, people, Earth
Carbon footprints: -Amount of CO2 emitted by an activity or an entity, Ecological footprints: Climate change, deforestation, overgrazing, fisheries
collapse, food insecurity, and the rapid extinction of species
Greenhouse effect: •Rise in earth's temperature, Atmospheric gases.
(Carbon dioxide, Methane, Water vapor), Traps the sun's energy.
Causes: Deforestation and agriculture, Burning of fossil fuels:
(gasoline,oil, etcetera), Burning of wood and coal, Population growth
Dangerous due: Global warming. Endangered species.Climate change.
To help; Reforestation. Personal Actions. Climate policy
Sustainable development: •A characteristic or state whereby the needs of the present and local population can be met without compromising the ability of future generations.
•A set of goals adopted by the United Nations in 2015 to end poverty, protect the planet, and ensure prosperity for all, as part of the 2030 Agenda for Sustainable Development.
Green consumers and non-green consumers:
•Willing to change their daily behaviors in an easy way.
•Committed with environmental issues.
•Willing to pay more
•Lack of awareness.
•Concerned about green consumers, energy consumption and the emission of CO2.
•Raising awareness (communication) and showing results.
•Don’t “greenwash” your company: image + content
•Explain what sustainability is for you.
•Put it into practice.
•Make your clients talk about the advantages of your company (fidelity).
•Help the community.
•Engineering: developing benign biofuels.
•Reinstalation of drinking fountains.
•Ecological products: food, cosmetics, clothes
•Environmental education: training for emergency plans
Examples of eco-friendly Business:
1.Terracycle: transform non-recyclable products into recyclable ones.
2. Looptworks: clothing made with recycled clothes.
3. Firecraytile: tiles with recycled glass
4. Ethnicraft: ecological furniture [http://ecoesmas.Com/ethnicraft-mobiliario
