Question

Over 400,000 people marched in New York City demanding action on climate change. What is next?

Answer

An amazingly diverse group of people walked in the People’s Climate March in New York City because we are just beginning to realize as a society how urgent it is that we take rapid action to protect the future of our civilization and human life on this planet.

Recent studies show that if we want to maintain a livable climate, there is a limit to the amount of fossil fuels we can burn. And at our current pace, we will hit that limit in just 30 years. That is a pretty sobering thought. The implications are clear – we will need to transition to a 100% clean energy, zero emissions economy in the next 30 years.

Emissions will need to peak soon and begin falling rapidly if we are to avoid catastrophic and irreversible consequences. The investments we make over the next 15 years will determine the future of the world’s climate.

The good news is that this transition is not only technically feasible, but will save us money, strengthen our economy, and provide tremendous health benefits. We have an aging fleet of power plants that were put in place in the 50’s and 60’s and now need to be replaced. We can choose to replace them with more fossil fuel plants and lock our emissions in for the next 50 or 60 years. Or we can make the choice to switch to clean energy power systems – now, today. We have excellent and viable alternatives.

We can put solar panels on our rooftops, parking lots, and landfills. And start driving electric cars. We can build wind turbines and use hydro to fill in the gaps. We can design our new buildings so they use far less energy and unlock the energy savings in our existing buildings. Every dollar invested in energy efficiency yields $4 in energy savings – up to $2 trillion dollars in savings from our commercial buildings alone.

If we choose to replace our aging fossil fuel power plants with renewable replacements and energy efficiency investments, the slightly higher upfront costs will be more than offset by the savings from our reduced fuel costs. And every dollar we spend on a clean energy future is a dollar that stays in our local economy.

We marched in New York City because we are the first generation to feel the effects of climate change and the last generation that can do anything about it. It is time to get to work.

Question

My electric rates are skyrocketing. What can I do?

Answer

Our electricity rates have become increasingly volatile due to our over dependence on natural gas. We saw our electricity rates rise 24% last winter and the trend is accelerating with the Mass DPU approving generation rate hikes of almost 100% for the coming winter. It is clearly time to diversify our energy portfolio.

The increased volatility of our electricity rates makes switching to solar and wind power increasingly attractive. In fact, solar has reached “rate parity” in Massachusetts. Many Solarize Lexington homeowners with good sunny roofs were able to save up to 75% on their electricity bills by locking in a fixed rate for their solar electricity for next 20 years.

For those of you without good sunny roofs, like your lucky neighbors, ask your elected representatives to support community shared solar projects, which will allow you to buy solar power from a nearby solar farm.
