Renewable Resources change
What is Renewable Resources? change
A renewable resource is a resource which can be used repeatedly and replaced naturally. Renewable energy almost never runs out, for example: solar energy is powered by heat from the sun and never runs out. Other examples include oxygen, geothermal power, fresh water, solar energy and biomass.
Gasoline, coal, natural gas, diesel, plastics and other fossil fuels are not renewable. They take millions of years to be made, and cannot be renewed in a human’s, or even a nation's lifetime. Ways have been developed to make biodegradable plastic and bio diesel and other fuels from renewable resources such as corn, sugar cane, soybeans and canola.
Renewable resource harvesting and use typically do not produce pollution or contribute to global warming. The use of renewable resources and energy sources is increasing worldwide, with certain nations, such as Bhutan, and US states, such as California, beginning to rely entirely on renewable energy. From 2008 to 2012, the U.S. doubled renewable generation from wind, solar, and geothermal sources. America and Britain are now home to some of the largest wind and solar farms in the world. There are also things called human resource where human’s waste is turned into energy. There are many other resources such as water power. Renewable resources are basically the opposite of non-renewable resource
Why renewable resources matter change
Renewable resources are pivotal in addressing the increasing demand for energy as the global population grows. They offer cleaner energy solutions, contributing to reduced greenhouse gas emissions and combating climate change. Let’s delve into the types of renewable resources
Types of Renewable Resources change
Sun
Sunlight, a widely recognized renewable resource, has been harnessed throughout history to warm shelters, cook food, and generate electricity. Solar photovoltaic devices, like solar cells, transform sunlight into electricity, powering appliances and homes. However, challenges arise due to variability and reliability, dependent on factors like time of day and geographic location
For example solar photovoltaic (PV) devices, or solar cells, change sunlight into electricity. Depending on the number of solar cells in use, they can power small appliances or provide the electricity for many homes
Wind
Wind energy is harnessed through turbines that convert wind’s kinetic energy into electricity. The sun’s heat drives wind patterns, making wind a direct byproduct of solar energy. While wind power offers emissions-free electricity, it requires careful environmental considerations, including potential impact on bird life.
In earlier years, windmills were used across the U.S. to capture energy and pump water from wells. They still exist in some farming areas to provide livestock with water.
Biomass
Biomass refers to renewable organic materials, like wood and agricultural waste, converted into energy through processes like photosynthesis. It’s an eco-friendly alternative to fossil fuels and can contribute to reducing carbon emissions.
Biomass renewable resources include wood and wood waste, agricultural crops and waste (which are mainly used for biofuel), municipal waste including paper, cotton, food, and yard waste, and animal manure and sewage.
