The problem is the cost of building such a grid says janusz bialek director of the centre for energy systems at skoltech institute of science and technology.
Clean energy sources problems.
However with a lack of massive metal turbines in wind turbines and no promise of consistent sun for solar farms there is a fundamental problem with renewable energy if the entire grid relied.
The state s historic shift away from fossil fuels such as natural gas which provide consistent power toward cleaner sources such as solar and wind energy which rise and fall with.
Entrenched special interests are fighting against renewable energy.
However renewable sources such as wind solar geothermal biomass and.
There are many reasons the world is looking for alternative energy sources in an effort to reduce pollutants and greenhouse gases.
Fossil fuels coal oil and natural gas do substantially more harm than renewable energy sources by most measures including air and water pollution damage to public health wildlife and habitat loss water use land use and global warming emissions.
If we do nothing to clean it up we condemn ourselves to facing the worst consequences of climate change.
It s clean because it has little or no waste products like carbon dioxide other greenhouse gases or chemical pollutants.
The problem with renewable energy.
Here are our main sources of renewable energy.
Renewable energy resources offer cleaner alternatives to fossil fuels.
Consistent power toward cleaner sources like solar and wind energy that rise and fall with the weather and the sun.
Clean energy includes renewable energy energy efficiency and combined heat and power.
Alternative or renewable energy sources show significant promise in helping to reduce the number of toxins that are by products of energy use and help preserve many of the natural resources that we currently use as sources of energy.
But progress isn t easy.
All energy sources have some impact on our environment.
The power sector is a leading source of cancer causing air pollution and the nation s second largest source of carbon dioxide.
