For example hydroelectric engines require rain wind turbines require movement in the air and solar panels need the sun.
Why don t we switch to renewable energy.
The combustion of fossil fuels for energy results in a significant amount of greenhouse gas emissions that contribute to global warming.
The current energy system on the other hand prioritizes short term economic revenues over all else.
When it comes to renewable energy there are two basic problems.
Clean energy has far more to recommend it.
Could switch to mostly renewable energy no batteries needed better electricity sharing across states would dampen the effects of variable weather on wind and solar power.
We cannot control when we receive it and how much we receive.
The number one challenge for renewable energy is the fact that in most cases it s not always on.
Most sources of renewable energy result in little to no emissions even when considering the full life cycle of the technologies.
It often relies on weather like the sun or water.
Unlike traditional nuclear or coal power plants which deliver predictable steady streams of electricity to.
That kind of intermittent generation wouldn t be a problem if we had a cost effective reliable way to store power but we don t yet.
You get power when it s sunny or windy and when it s not you don t.
Renewable energy is also not completely reliable even though it is sustainable.
With alternative energy still being a relatively new idea it has yet to be made as cost effective as existing.
That means that there.
What it carries however are the long term benefits that will hopefully be realized when it takes over fossil fuels.
As a result renewable energy prices can be very stable over time.
Well first and foremost the entire energy production industry is absolutely massive.
That s because renewable energy sources such as solar and wind don t emit carbon dioxide and other greenhouse gases that contribute to global warming.
3 reasons why we haven t switched to alternative energy inertia.
Moreover the costs of renewable energy technologies have declined steadily and are projected to drop even more.
