Marcus is writing an essay about recent positive developments in home solar power installations. Which two sentences would best conclude his essay?
Our reliance on so-called "dirty power," which is power generated by the burning of fossil fuels such as coal or gas, is a growing concern among the worldwide community, from governmental leaders on down to the average citizen.
In the final analysis, the sharp rises in the cost of power provided by our utility companies and the projected even sharper rise in those rates in the future is an issue of great concern to many and one which governmental authorities should better address.
A prominent solar power company recently announced a revolutionary new product, a whole-house battery, which is a wall-mounted storage unit that allows one to collect power during low-use times and then use it during peak hours.
Now that whole-house batteries are available on the market, there is greater incentive than ever for homeowners to consider a solar power installation, and the closer we get to moving "off the grid," the more everyone will benefit.
Overall, the free installations offered by solar companies, tax credits and rebates from the federal government, and power credits from utility companies make going solar vastly more affordable than it used to be.
