Solar, Wind, or Hydro Energy – Which Renewable is Right for You?

Solar, Wind, or Hydro Energy – Which Renewable is Right for You?

What Makes Energy Renewable?

As many of us notice the effects of our changing climate, we’re becoming more environmentally conscious. Our global community is coming together to find the best environmentally friendly way to protect life on earth, like renewable energy. 

You may be wondering what makes energy renewable or not? Renewable energy is energy that comes from a source that isn’t finite. For example, sun, wind, rain/water, heat, and waves are all sources of renewable energy – with a little help from some cool technologies. Non-renewable energy is finite, which means we’ll run out of it eventually and have to change how we power our lives. Fossil fuels are non-renewable energy sources. We’ve been using fossil fuels as a source of energy as long as humans have been around, like our use of coal or wood for fires in the home.

However, as our world grows the amount of fossil fuels we use to power everything from our homes to global trade has increased. With so much relying on fossil fuels we’ll eventually use up that supply. But our world won’t stop growing, so we need to come up with ways to power our homes and lives that don’t rely on fossil fuels.

Thankfully we can turn to renewable energy, which stays constant and will be here as long as the earth is. Using renewable energy also reduces the pollution from sources like CO2 emissions, which is great for all of society because it will help address climate change related issues like droughts, wildfires, and flooding that threaten our homes and communities. 

In the U.S., the most common renewable energies for use at home are solar, wind, and water. As a homeowner interested in powering their home to clean energy, you may be asking which is best for your home?

What is Solar Energy?

As you may guess from the name, solar panels absorb sunlight and then convert that into electricity through a process called the photovoltaic effect. With the sun always around to help photovoltaic (or PV) panels create electricity, they’re fast becoming a popular power source. Solar energy has been one of the fastest-growing sources of renewable energy in 2020 solar generation made up 3.3% of the total US generation

Solar energy can be used to power homes, businesses, cars, aircraft, and the electronic devices we use in our daily lives. How much can solar energy power? According to the U.S. National Renewable Energy Laboratories (NREL), the amount of energy from sunlight that hits the Earth in one hour could supply the world’s energy needs for an entire year!

With solar becoming more widely available and used in homes, and technology becoming more advanced, solar also becomes more affordable for homeowners. More people are able to make the switch to solar and take advantage of solar’s long-term benefits. The industry-standard lifespan of solar panels is about 25-30 years, which means you’ll likely have them for as long as you live in your home.

What Are the Benefits of Switching to Solar?

Homeowners who switch to solar can see a lot of benefits, including:

  • Renewable energy has lower emissions (CO2 or other greenhouse gases) than traditional power sources. You’ll get the electricity you need, without worrying about how you’re impacting the earth. 
  • With technological updates, solar is becoming more affordable for homeowners – and Purelight Power’s $0 out-of-pocket solar makes it even more affordable for customers to make the switch to solar. 
  • Solar is sustainable and will always have its energy source: the sun
  • Solar adds equity to your own home and increases its value by upwards of 4%. 
  • Low maintenance – other than cleaning your panels a few times a year, there’s not much maintenance involved. 
  • Right now, it’s extra affordable! Current federal and state tax incentives, and rebate programs help you switch to clean solar energy for less! 

Cons

  • You’ll need a fair amount of space, like your roof, in order to offset your power bill by 94% or more so you no longer have to pay the power company.
  • Weather can affect your panels’ energy production. When there’s not a lot of light from the sun, like cloudy, rainy, and snowy days your panels can’t perform at maximum capacity. The good news is, with net metering you can draw on the extra power you did produce during sunny days!
  • To some homeowners, solar panels aren’t pleasing to the eye. But a slightly different look to your roof might be offset by bragging rights of owning your power and being the greenest house on your block.
  • You can’t take a rooftop home solar system with you. So if you’re planning to move soon, unless you want to immediately increase the value of your home by 4% or more, making the switch to solar right now might not be for you. 

Right now, solar is more affordable than ever for homeowners with tax incentives from state and federal governments that only last through the next year (or less). Coupled with Purelight Power’s zero down program, homeowners can wipe out their power bill and stop renting electricity from greedy power companies.

Solar, Wind, Water Renewable Energy

How do we use water for renewable energy?

According to the Office of Energy Efficiency and Renewable Energy, “hydropower is the most widely-used renewable power source, accounting for more than 37% of total U.S. renewable electricity generation and about 7% of total U.S. electricity generation.” Chances are, especially for homeowners in the US, you’re already getting some of your electricity from hydropower.

Hydropower, or hydroelectric power, is a renewable source of energy that generates power by using a dam or another structure, such as a turbine set in the ocean, to turn moving water into electricity. Did you know, hydropower is one of the oldest renewable energy sources used widely in the U.S?

But how does water become electricity? As the water passes through a turbine’s blades, it starts the generator to convert the motion of the water into electricity. If you have water flowing through your property, you might consider building a small hydropower system to generate electricity. A micro-hydropower system needs a turbine, pump, or waterwheel to transform the energy of flowing water into rotational energy, which is converted into electricity.

Benefits

  • Hydropower uses water to generate electricity, so it’s a clean source of energy.
  • If you have natural running water next to your property you would be able to use that natural resource as a form of energy and not have to rely on an outside source of energy.
  • Hydropower at the community level often creates reservoirs that offer public recreational opportunities, like fishing, swimming, and boating. Clean energy and fun on the water? Win-win.
  • As an energy source, hydropower provides more than just electricity. The reservoirs created by hydropower using dams also provide clean drinking water, flood control, and irrigation support.
  • Currently, hydropower is one of the most efficient energy sources. Hydroelectric dams are about 90% efficient at converting water into electricity.

Cons

Wind Energy

Not just for the windy city, wind energy from wind turbines convert the energy that is produced from the motion of the wind, into mechanical power. Then a generator can convert mechanical power into electricity. Wind turbines work almost as engines do, the winds start to spin the propellers, the propellers then start to spin around a piece called the rotor, which turns the drive shaft which turns an electric generator. 

Three factors affect the amount of energy that can be produced from the wind: wind speed, air density, and swept area. Because of this, wind energy is best suited for areas with regular high winds – like off the coast, in deserts, or throughout the American prairies.

Benefits 

  • The wind is clean and renewable energy which, like solar and hydro, doesn’t directly emit greenhouse gases like burning fossil fuels. Also, wind is something that will continuously exist. But with that being said there are plenty of days where there is no wind at all. 
  • Once you install a wind turbine or wind farm it has low operating costs since the power source itself is free. Although you will have to pay for routine maintenance done every six months, and eventually replace the whole system around 20 years.
  • Wind turbines don’t take up much space on the ground. Like solar, they can be placed in areas where they don’t get in the way, like being placed on your roof or on the ground.
