renewable resource

Examples of renewable resource in the following topics:

• Types of Natural Resources

  • Renewable natural resources: these are resources that can be replenished.
  • Examples of renewable resources include sunlight, air, and wind .
  • Non-renewable natural resources: these resources form extremely slow and do not naturally form in the environment.
  • Examples of non-renewable natural resources are minerals and fossil fuels.
  • Wind is an example of a renewable natural resource.

• Genomics and Biofuels

  • Although plants are renewable resources, there is still a need to find more alternative renewable sources of energy to meet our population's energy demands.
  • The microbial world is one of the largest resources for genes that encode new enzymes and produce new organic compounds, and it remains largely untapped.

• World Energy Use

  • The most prominent sources of energy used in the world are non-renewable (i.e., unsustainable).
  • shows a pie chart of world energy usage by category—both renewable and nonrenewable sources.
  • Renewable energy comes from sources with an unlimited supply.
  • In the US, only 10% of energy comes from renewable sources (mostly hydroelectric energy).
  • For example, by the year 2020 Germany plans to meet 10% of their total energy usage and 20% of its electricity usage with renewable resources.

• Present Sources of Energy

  • Present sources of energy include fossil fuels, various types of renewable energy, and nuclear power.
  • Most of the world's energy resources are from the conversion of the sun's rays to other energy forms after being incident upon the planet.
  • The estimates for remaining non-renewable worldwide energy resources vary; the remaining fossil fuels total an estimated 0.4 YJ (1 YJ = yottajoule, or 1024 J) and the the energy available from nuclear fuels such as uranium exceeds 2.5 YJ.
  • The total energy flux from the sun is 3.8 YJ/yr, which dwarfs all non-renewable resources.
  • Renewable energy sources only comprised 16.7% of our energy in 2010.

• Overharvesting

  • Overharvesting, also called overexploitation, refers to harvesting a renewable resource to the point of diminishing returns.
  • All living organisms require resources to survive.
  • Overharvesting these resources for extended periods of time can deplete natural resources to the point where they are unable to recover within a short time frame.
  • Overharvesting not only threatens the resource being harvested, but can directly impact humans as well - for example by decreasing the biodiversity necessary for medicinal resources.
  • The natural outcome of harvesting common resources is their overexploitation.

• Economic Activities

  • Some resources, like solar or wind, are referred to as "flow resources. " If the resource is used for one purpose, there is no significant impact on the availability of the resource for other uses.
  • Other land resources are called "renewable. " A forest, fishery, herd of buffalo, whales, water quality and the like are renewable resources.
  • Fish, whales and buffalo (and other wildlife) can be harvested and if a large enough population is left it will "renew" or replenish.
  • Other resources are called exhaustible resources.
  • Coal and oil are examples of these resources.

• New Energy Sources

  • Alternative and renewable energy sources can reduce the environmental impact of energy production and consumption.
  • Renewable energy is energy that comes from natural resources, such as sunlight, wind, rain, tides, waves, and geothermal heat, which are all naturally replenished.
  • The share of renewables in electricity generation is around 19%, with 16% of global electricity coming from hydroelectricity, and 3% from new renewable sources.
  • While many renewable energy projects are large-scale, renewable technologies can also be suited to rural and remote areas, where energy is often crucial in human development.
  • Ethanol is a quasi-renewable energy source.

• Types of Social Responsibility: Sustainability

  • Sustainability is the capacity to endure over the long term through renewal, maintenance, and sustenance.
  • It also encompasses stewardship for natural resources, such as trees and wildlife.
  • Sustainable business practices consider not only the use of resources in production, but also the assurance that those resources can be replenished for future use.
  • Reducing greenhouse gasses harmful to the atmosphere and embracing alternative, renewable fuel sources such as wind and energy are examples of business practices in this area.
  • This means companies' operational practices reduce environmental damage and resource depletion.

• Introduction

  • Hartman gathers many different types of resources to target different types of learners in Mrs.
  • Russell, with its multitude of available resources, is the epitome of a Resource-Based Learning (RBL) unit.However, resource-based learning is not tied to a single learning theory or to any specific pedagogy (Hill & Hannafin, 2001; Ling, 1997).Nor is it new to teaching and learning.
  • What, then, is resource-based learning?
  • White planned this unit around resources, her students had little opportunity to direct their own learning.Although the resources probably enriched the unit and raised the interest level of many students, Ms.
  • Russell's Civil War unit is a better example of resource-based teaching.The remainder of this chapter will address resource-based learning at the more student-centered end of the continuum.
