Exploring Different Types of Eco-Friendly Electric Generators: Solar, Wind, Hydro, and More


Our world is growing more and more concerned with the issue of climate change, continually looking for sustainable energy solutions. We see an emerging alternative in eco-friendly electric generation to the base of traditional, mostly fossil fuel-centric methods of power.

These fresh, renewable setups come in many types. In this write-up, we’ll help you get a better sense for the kind of eco-friendly electric generator types that are out there, what they do best, and, most of all, how clean they are in comparison to power sources of the past.

1. Solar Generators: Harnessing the Sun’s Abundant Energy

Perhaps the most recognizable of the green electric generators, solar, is just what its name might suggest. It is electricity derived from the near-constant stream of sunshine that falls onto photovoltaic (PV) panels. Solar electricity can, of course, be used right away, straight out of a theoretical socket, but a lot of usages do a lot better if they’re stored until needed in big old battery banks. Photovoltaic electricity is not the kind of portable power source you take with you that runs on liquid or gas fuels. Instead, it is an exhaustible, near-silent, and very versatile kind of back porch power plant.

2. Wind Generators: Capturing the Power of the Wind

Wind electricity generation is frequently the cleanest means of producing electric power in communities around the planet. Wind power is a global industry—an industry that is currently enjoying double-digit growth. It demands intensive capital to get started. Once the projects are built, much of the payoff comes from two simple facts: wind and sunlight are free, and wind turbines do not pollute. They are the cleanest, “round-the-clock” non-polluting power source. While many other so-called “clean” or “renewable” options generate power most of the time, wind turbines generate power all the time provided there are no cut-off wind speeds when the turbine simply cannot operate safely.

3. Hydroelectric Generators: Harnessing the Flow of Water

Electricity is generated from the power of river water in motion. There are several ways you can achieve this, but the two main methods are by using a dam to create a very large reservoir of water and then releasing that water through very large turbines or by doing the same thing with very large natural rivers and streams. Established long ago as a reliable and renewable source of electricity, hydroelectric power plants are now the reason why many non-traditional power plants create the way they do.

4. Biomass Generators: Utilizing Organic Matter

Converters harness plant power to make electricity. Today’s biomass power plants work on the same principles as yesterday’s coal-fired power plants. They burn a feedstock to create the same byproducts—steam and heat. Since biomass is not a fossil fuel, it doesn’t leave us with quite the same mess (even though it produces other emissions in the burning phase). Because we’re not using 540 million-year-old material, power derived from plant waste and dedicated energy crops is considered carbon-neutral.

5. Geothermal Generators: Tapping into Earth’s Heat

Electricity is generated from geothermal energy that is released from the Earth’s core. The energy is in the form of heat and is used to produce the steam that turns the turbines connected to generators. No matter what the weather is doing, and 24 hours a day, seven days a week, geothermal power plants can rely on the heat deep within the Earth to make a constant supply of electricity. However, only certain parts of the world have the kind of geology where this works.

Choosing the Right Eco-Friendly Electric Generator

The perfect green generator really depends on a few different things. What are you going to be using the generator for? Do you know how much electricity, in general, your world consumes? Because you can’t just look at your appliances and say, “Oh, that one uses 5 kilowatt-hours a day.” You really have to do a kind of audit of your electricity use. Then you’ve got to look at the resources that are available where you are. Are you somewhere incredibly sunny? Do you live on a crest where it’s always windy? Are you on the beach where wave power might be possible? Once you’ve done your audit and assessment, then you start looking at the actual machines that might fill the bill.


We are in the middle of an energy revolution. Leading the charge are so-called “renewable” or “green” electric power sources. In this revolution, the sustainable, environmentally friendly generators are a direct and potent alternative to the traditional power plants that run on fossil fuels. The renewables come in many forms, and it seems that every one of those forms has a magazine or a website pitching for real estate on your rooftop or in your backyard. Led by the luminaries of the sun and the wind, as well as their sweaty publicists, each of those forms is a perfectly nice, perfectly ordinary generator.
