Americans are bracing for expensive energy bills this winter — President Biden has even offered billions of dollars in aid as the economy faces high inflation.

Families can use smart home technologies and lock doors, seal cracks, remove air conditioners, and more. As we look for ways to reduce energy costs through best practices like

In short, solar panels help convert sunlight into electricity.

“Solar technologies convert sunlight into electricity through photovoltaic (PV) panels or mirrors that concentrate solar radiation. This energy can be used to generate electricity or stored in batteries or thermal storage,” – Energy Efficiency and Renewable Energy Administration ( EERE) describes.

What are 3 advantages of going to the sun?

Before you take the plunge and completely change your habits, you probably want to know more about solar energy and why more families are starting to incorporate it into their lifestyles.

Here are three compelling reasons to go solar today:

The cost of using solar energy has fallen
Save energy costs
Reduce your carbon footprint

The cost of using solar energy has fallen

At one point, cost was the main reason homeowners hesitated to install solar panels. However, times have changed – and prices have been falling for years. EERE says the cost of solar power is falling every year.

According to the Solar Energy Industries Association (SEIA), solar installation costs have fallen by more than 60% in the past decade. Solar power isn’t just popular in sunny states like California or Florida. States across the country have started using solar energy.

The cost of solar equipment is generally calculated by comparing dollars per watt.

“The average residential system has fallen from $40,000 in 2010 to about $20,000 today, with recent utility prices ranging from $16/MWh to $35/MWh, competitive with all other forms of generation.” SEIA explains online. This total cost does not take into account the tax incentives associated with using solar energy.

Save energy costs

Another major reason to go solar is to save on energy costs. According to the National Association of Energy Assistance Directors, the typical cost to heat a home this winter will increase 18% — to about $1,208, hitting lower-income households harder.

Although you will have to spend money to install and properly install solar panels, you should see a significant difference in your utility bills by going green.

Community solar can lead to bill savings of 5% to 25%, according to the National Renewable Energy Laboratory (NREL) 2021 report, Sharing the Sun: Community Solar Deployment, Subscription Savings, and Energy Load Reduction.

EnergySage, a Boston-based solar energy company, estimates that most solar users can save between $10,000 and $30,000 over the life of their solar system.

Total savings depend on your location (the amount of sunlight available), the type of solar energy system you use, the amount of electricity you use, the size of your home, whether you bought or leased your system, your local utility, and more. Take a look at your utility bill. Then consider how many watts your household uses to determine potential savings.

Reduce your carbon footprint

Apart from the many benefits that solar energy will provide you financially, it will also benefit the planet.

“Each kilowatt-hour (kWh) of solar energy produced will significantly reduce greenhouse gas emissions such as CO2, as well as other hazardous pollutants such as sulfur oxides, nitrogen oxides and particulate matter. Solar energy also reduces water consumption and withdrawal,” – US Energy The department provides information online.

The solar revolution continues successfully. The cost of solar power has been falling sharply for years and is now the cheapest form of new electricity generation in many markets, including 16 US states, Spain, Italy and India, according to energy research and consulting firm Wood Mackenzie. Even during the pandemic, solar development remained strong. In 2020, global solar installations exceeded 115 gigawatts (GW). Although the price of solar panels increased last year, the cost of solar energy still managed to fall in 2021. While solar expansion continues to grow at increasingly competitive rates, it has not been fast enough or serious enough. The growth trajectory required to achieve the decarbonisation targets set by the Paris Agreement in 2015. Instead, the renewed revolution was met by a massive and seemingly immobile force of inertia.

In addition to the pushback from powerful fossil fuel lobbies and their allies, the current energy system already invests heavily in fossil fuels, and continuing to operate a coal- or gas-fired plant is often much, much cheaper than building new solar infrastructure. may be new infrastructure. In addition, “There is a lot of inertia in the system because of long-term contracts between utilities, power producers and mining companies,” Popular Science reported last year. “And since the country’s total energy use isn’t growing that much each year, there’s not much incentive to build new renewables.”

In order to break all this internal inertia, the global economy had to deliver a major shock to the system. Now we have it. The double whammy of the Covid-19 pandemic and Russia’s illegal invasion of Ukraine sent shockwaves through the global economy, throwing energy markets into turmoil and scrambling for alternatives to Russian exports to keep the lights on and restore energy security. And many have set their eyes on the sun to do it.

In Europe, 18 of the 27 European Union countries set new records for solar power generation between May and August this year, and the bloc is set to see an average annual increase of between 45 GW and 52 GW by 2030 – a huge increase. compared to pre-occupation projections. In the United States, the Inflation Reduction Act offered major tax incentives for clean energy development, and solar investment is increasing in response. Consulting titan McKinsey predicts that global renewable electricity capacity will almost triple between 2021 and 2030 to 8,800 gigawatts. The vast majority of this will come from onshore wind and solar.

While incentives and investment are available, the renewable revolution faces three major obstacles as it continues to expand at a rapid pace: land, permits and energy grids.

Soil can be the biggest of these problems. “Utility-scale solar and wind farms require at least ten times more land per unit of energy than coal- or natural gas-fired power plants, including the land used to produce and transport the fossil fuel,” warns Mckenzie. solar investors. Indeed, the expansion of renewable energy is already embroiled in land-use battles across the country, as projects are often developed in rural states that are often deep red and devoted to fossil fuels. A “sinister” battle is currently underway in Indiana, where a solar farm roughly the size of Manhattan is in the works.

Expansion is also hampered by “long, unpredictable development rules” beyond developers’ control, McKinsey says. Permitting is a daunting process, as legislation often changes to match the kinds of public outrage that emerges in response to land use issues. As a result, permits for utility-scale solar and wind farms can often take up to ten years. 31 states have already passed ordinances limiting renewable expansion.

Finally, increasing network congestion poses a major threat. The energy grid infrastructure in the US is aging and will need major infrastructure investments to accelerate it. Our grid system is now not smart or flexible enough to handle the dynamic and changing nature of massive reliance on renewables. This will require a huge increase in energy storage technologies. “Because the stability of the electricity grid depends on predictability and the balance of supply and demand, the US grid cannot always integrate all new wind and solar power immediately,” McKinsey reports. This means that completed solar projects often have to wait months before they can be connected to the grid. Moreover, the urban areas most in need of energy are often far from the rural areas where this large amount of clean energy will be produced, requiring large expansions of transmission lines to deliver power to end users.

While the rapid expansion of utility-scale solar and wind projects is a long overdue necessity to meet climate goals and avoid the most devastating impacts of climate change, there are some serious obstacles to consider. And that will require some major politics at a time when the country has never been more divided.
