While renewable energy might be expensive to first implement, the savings over time more than make up for it. As more sources of renewable energy are integrated into the power grid, the cost of energy has the potential to decrease, along with making the planet less susceptible to greenhouse gasses.
Renewable energy comes from natural processes, such as the wind, water, or sunlight. Since all these resources depend on the time of the year and weather, having more than one type can keep the grid stable. While these sources are still more expensive than coal and fracked gas, with a more complete infrastructure, they become less expensive over time. However, there are still a lot of myths about green energy that hold back companies and governments from implementing them. Let's debunk some of these myths.
Myth #1: Renewable Energy is Unreliable
Many people believe that renewable energy is unreliable because the weather can be unpredictable. However, we now have more efficient and powerful ways to store energy. For example lithium-ion battery cells can store more electricity for a longer period of time compared to other batteries.
Myth #2: It’s too Expensive to Transfer to Renewable Energy
While creating the original equipment to supply a grid with renewable energy does have a high cost, the cost of using it decreases over time. With coal or fuel, you need someone constantly mining or drilling to keep the flow moving. With renewable energy, you barely have work to do once everything is put in place – with the exception of maintenance.
Myth #3: Renewable Energy is Harmful to the Environment
Making renewable energy requires some greenhouse gas emissions, land use and water consumption. However, researchers found that all renewables show emissions of anywhere from 14 to 134 times lower than the energy created with fossil fuels. Some, such as solar and wind energies, do not emit any greenhouse gasses – however, if fossil fuels are used to create the wind turbines and solar panels, that must be added in. The production of green energy also does not emit pollutants such as dust, black carbon and heavy metals.
Myth #4: Renewable Energy is Infinite
While the sun, wind and water from the ocean might be infinite, the hardware is not infinite. However, using recycling practices, lithium for batteries, copper, and other goods that need to be mined, can make renewable energy last longer.
Myth #5: Renewable Energy Cannot Replace Fossil Fuels in the Heavy-Duty Sector
Most people do not believe that renewable energy can be completely replaced, especially in the transportation sector. Large equipment used in construction and planes are two of the modes of transport that would be impossible to convert. However, increasing energy and conservation efficiency would actually decrease the need for fossil fuels needed to power large equipment and planes.
