You can choose the one that suits your needs best.
So what is Renewable Energy?
Renewable energy is derived from sources that are continuously replenished in nature. These sources include sunlight, wind, water (hydropower), geothermal heat, and biomass. The primary distinction between renewable energy and non-renewable energy lies in their ability to regenerate over time. Non-renewable energy sources, such as coal, oil, and natural gas, take millions of years to form and cannot be replaced once depleted.
Sources of renewable energy
There are many sources of renewable energy available to the average home. Wind energy is one example. Wind turbines can generate enough electricity for the average family to use for an entire year. Technology is improving all the time.
Hydropower is another renewable energy source that depends on swiftly descending water to produce electricity. It is also a cost-effective source.
Hydropower is one of the most widespread renewable energy sources and is used widely in many countries.
Another advantage of renewable sources of energy is that it is less polluting. The production of new factories is increasingly being measured based on carbon emissions. Solar panels, for instance, capture solar energy and convert it into electricity.
Solar collectors can be of different types depending on the source. It also generates heat and light, making it a useful source of energy for buildings and homes. But what are its disadvantages? It's important to note that solar energy has a long way to go before it becomes a widespread resource.
Wind turbines capture and transform the kinetic energy of wind through a complex mechanism. Biomass, on the other hand, is organic material from plants and animals. This biomass contains stored solar energy. When burned, biomass can generate heat and electricity.
Biomass can be used for a wide variety of fuels, including biodiesel and ethanol. Unlike fossil fuels, biomass is renewable, because new crops can be grown within a relatively short time.
One of the oldest sources of renewable energy is hydropower. Its infrastructure is long-lasting and consistently produces electricity. Hydropower is the cheapest source of renewable energy. Wind and solar power are expected to reduce hydroelectricity's cost and lead to a further exponential growth.
The world's largest renewable energy source is hydropower, but the two are now closing the gap in terms of overall energy production capacity. If solar and wind energy keep improving at the same rate, hydropower will soon be obsolete.
Wind energy is an ever-flexible source of energy. It was first used to perform mechanical tasks, such as pumping water from wells or grinding grains. Windmills are still in use today, though not at full capacity.
Solar energy, on the other hand, is a flexible and reliable energy source that powers many aspects of our lives. It can be warm water used for cleaning and bathing. Solar panels can also generate electricity for lights and appliances.
Wind and solar energy are the fastest-growing renewable energy sources in the U.S., and they accounted for more than a fifth of utility-scale electricity generation in the first quarter of 2021. These sources will make up almost half of all new electricity capacity in the U.S. by 2020.
Renewables will continue to grow at a rapid rate, as solar and wind power have become more affordable. The use of renewable energy is growing dramatically in the transportation sector.
Stock-limited nature of renewable energy resources
As the cost of fossil fuels continues to rise, the need to reduce them is increasingly urgent. Yet renewable energy sources like wind and solar are not without their drawbacks.
While biomass is touted as a renewable source, it can cause environmental issues by competing with land for food production. In addition, hydroelectric production is limited by the volume of water available in rivers. Climate change will eventually cause rivers to dry up and water supply to drop, making the future of this renewable energy resource uncertain.
Because renewable energy resources replenish themselves naturally, their availability is practically unlimited. Despite their seemingly inexhaustible nature, their use may be limited by their limited supply and time span.
Such resources include wood, hydro, solar, and geothermal energy. They may even include wave action technologies. Utilities can use renewable energy resources for many different applications, including bulk, distributed, non-grid generation, and demand-reduction.
One major concern with renewable energy is the stock-limited nature of the resources. Although they can be costly to produce, these sources also create jobs. As long as their production and consumption rates are kept in proportion to their replenishment rates, they can help reduce the overall cost of energy.
Even if there is a shortage of renewable energy resources, these resources are never completely depleted and are refilled faster than they are consumed.
A common concern with these renewable energy resources is how to develop them in a way that will maximize their supply. This means developing policies to encourage their use. In many countries, these policies include priority dispatch, special feed-in tariffs, quota obligations, and energy tax exemptions.
These policies are meant to promote the development of renewable energy resources. But what about the availability of geothermal energy? There is no widespread geothermal resource.
Cost of converting to renewable energy
The cost of converting to renewable energy is huge compared to fossil fuels. The US alone would need 1,085 gigawatts of solar and wind power to produce enough electricity to power the entire country.
Solar power can only generate electricity during daylight hours, while wind power provides power during nighttime hours. The cost of converting to renewable energy is likely to decrease over time, but the initial cost is quite high. And the cost of constructing new solar and wind facilities is very expensive.
The cost of developing a large-scale solar project can cost $0.10/kWh, but it is still cheaper than coal. IRENA says that renewables will become competitive with fossil fuels by 2020.
The cost of developing a CSP plant varies from $0.10/kWh to $0.27/kWh, but the average cost of developing one is about $0.18/kWh. That is not a lot, and it makes renewable energy an attractive option for many.
WoodMac's report also suggests that the conversion to renewable energy will increase the cost of the electric grid. It would cost approximately $700 billion to build out the necessary infrastructure. For this conversion to occur, the cost of constructing transmission lines would have to be 400,000 miles long, which would take many decades.
A massive infrastructure would need to be constructed, resulting in even higher costs for the consumer. But that isn't the only cost of converting to renewable energy.
The cost of converting to renewable energy has many benefits. The first step is to switch away from fossil fuels. It would be impossible to save money on fossil fuels alone unless there is a global transition to renewable energy.
And the second step in converting to renewable energy is to phase out older methods of generating energy. And the transition will be much easier if the U.S. can transition to renewable energy by 2050, even though the initial investment is higher.
