As the debate rages on about how to harness sustainable energy without causing harm to the environment, one source keeps coming up as the obvious solution – renewable energy. But is it really the answer? Or should we look elsewhere? Let’s take a closer look at renewable energy and whether it’s truly the best way to solve our green energy problem or not.

what is renewable energy?
Renewable energy is energy that comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat. Solar, hydroelectric, and wind are all examples of renewable energy. Non-renewable energy comes from fossil fuels such as coal and oil. Burning these fossil fuels releases harmful pollutants into the atmosphere. Renewable energy is a cleaner alternative to fossil fuels because it doesn’t pollute the air. It’s also a more sustainable option because it can be replenished. Solar panels convert sunlight into electricity, while wind turbines harness the power of the wind. Hydroelectric dams generate electricity from waterfalls. Geothermal plants use heat from the earth’s core to produce power.
Why there’s a green energy problem
The answer to whether renewable energy is the answer to our green energy problem is a bit complicated. While renewable energy is a source of clean, green energy, it currently only accounts for a small percentage of the world’s energy needs. Solar and wind power are the most common forms of renewable energy, but they are also intermittent, meaning they only produce electricity when the sun is shining or the wind is blowing. This means that traditional forms of backup power, like natural gas or coal, are still needed to supplement renewable energy when there’s no sun or wind. Another issue with renewable energy is that it can be more expensive than traditional forms of energy. This is because renewables require a significant upfront investment in things like solar panels or wind turbines.

Why renewables are the solution
The world is in a climate crisis, and we need to find sustainable, renewable sources of energy that won't damage the environment. Solar energy, wind energy, and geothermal energy are all great options that can help us achieve this goal. Not only are they environmentally friendly, but they're also increasingly affordable as technology improves. Investing in renewable energy is not only the right thing to do for our planet, but it's also a smart financial decision.
##How Renewables Are Already Fighting Climate Change
According to the Environmental Protection Agency, renewable energy is defined as energy sources that are naturally replenished on a human timescale, such as solar, wind, and water.
In 2015, renewables accounted for about 10% of our total electricity generation in the United States.
Solar photovoltaic (PV) panels and wind turbines are two technologies that are often used to generate renewable electricity.
Solar PV panels convert sunlight into electricity, while wind turbines capture the kinetic energy from moving air and convert it into electricity.
While these technologies have been around for a while, their costs have decreased significantly in recent years, making them more viable options for fighting climate change.
What We Need To Do To Fight Climate Change
We need to wean ourselves off of fossil fuels and move towards renewable energy sources. But is renewable energy enough to save our planet? Solar and wind energy are great, but they're not always reliable. We need to find a way to make them more reliable so that we can rely on them for our energy needs. One way to do this is by developing technology that stores power when it's produced and then releases it when it's needed most. Another option would be to build more nuclear power plants that generate their own electricity with no greenhouse gases at all.
