I was reading an article titled "Wind energy turns out to have a complication: reliability" It states that the biggest problem with wind is that it doesn't blow when it's needed most. The biggest strain on the energy grid is hot summer days when everyone is running their air conditioners. Of course it's these same days that the wind doesn't blow. The article goes on to suggest a few alternatives none of which are very good. We could create Hydrogen, a clean way to create Hydrogen, is a plus and if there is any surplus green energy, it should be used to create hydrogen, but we are not at that point. Another alternative is pumping air into underground chambers to help power natural gas plants, and turning off Hydro electric plants to allow the hydro power to be used when the wind is not blowing.
My opinion is that they are thinking on the wrong scale. Don't worry about making the central grid more powerful, worry about making the end user more self reliant. We already have Heaters, air conditioners, and water heaters at every house. Why not add a battery pack? Let's make every house self sufficient for 2 or 3 days. A power outage is only a problem because people cannot keep their house heated. The giant storms that have moved through this winter would be almost nothing if the houses all still had the ability to power themselves for a few days.
Then the purpose of the central power grid is to recharge a houses battery. If a battery is dead the house will use power from the grid for the house, then at night the battery can recharge. I'm not talking about giving every house a generator. I'm talking about a battery. The same way that a Prius can be used to power a house, a batter could be used to power a house.
When every house has it's own battery, then solar power can be used to recharge the battery without needing power from the grid. If the battery is fully charged then the house can get power from the grid.
Can you imagine it? No more brown outs. No more blackouts.
