• Energy resources


  Resources that naturally occur in the planet that help humans to get energy in the form of mostly electricity while natural conditions are favorable
• Energy resources


  • Coal
  • Oil
  • Wood
  • Gas
• Renewable resources


  • Wind
  • Solar
  • Hydroelectric
  • Wave power
• Renewable natural resource


  Resources that are replenished by nature over a relatively short period of time
• Renewable resources are far better to utilize since they typically renew so quickly that by the time we have used it out, it will have been replenished
• Solar energy


  The sun's radiance in the form of heat and light, which is captured using a variety of technologies such as solar panels, solar heating, and photovoltaics
• Renewable energy projects


  • Negros Solar Farm
  • Mindoro Wind Farm
  • Isabela Hydropower Plant
  • Makban Geothermal Power Plant
• Wind energy


  May be utilized to propel wind turbine blades and then converted to electrical current for power generation
• Wind energy has no pollution, but it is not practicable in regions where there is little or no wind
• Water


  An extremely valuable renewable resource that exists on Earth in many different forms: as a liquid in the seas, as a solid in our polar ice caps and glaciers, and as a gas in clouds and water vapor
• Water is utilized to generate hydroelectric power, which is obtained by damming water
• Geothermal energy


  A sustainable source of energy from the Earth's volcanoes, which erupt and spew lava
• The heat from within the earth escapes through cracks in the crust, which are generally quite thin
• Renewable natural resources


  • Plants
  • Animals
• Plants are utilized for food production and product manufacturing, and they can be replenished after harvest
• Animals, like plants, are a renewable resource since they can be bred to grow their number
• Biofuels


  Biological fuels that are derived from living organisms, such as ethanol from maize and biodiesel from vegetable oil
• Biofuel sources


  • Firewood
  • Animal dung
  • Peat
• Non-renewable resources


  Coal, petroleum, and natural gas
• Fossil fuels, which are the most common non-renewable energy sources, were formed hundreds of millions of years ago from the remains of plants and animals that were crushed under extreme heat and pressure
• When coal and petroleum are burnt


  Particulates are released into the air, water, and land that can contaminate the environment
