Guide to Buying Energy Efficient Light Bulbs as Daylight Savings Time Ends
An uptick in energy consumption is inevitable with the the end of Daylight Savings Time coming this Sunday.
The majority of the U.S. will gain an extra hour Nov. 3 when our digital clocks move back an hour at 2 a.m. As fall and winter carry on, the days will get shorter and require more lighting in our homes. Emphasizing the importance of efficiency, the Natural Resources Defense Council released a light buying guide this week to encourage U.S. residents to consider the most efficient options—and the savings that come with them—when they stock up on bulbs.
“This time of year offers an excellent opportunity to review our lighting and switch to the new and improved light bulbs that have recently entered the market," said Noah Horowitz, senior scientist and director of NRDC's Center for Energy Efficiency.
“Just because it's the end of Daylight Savings Time, it doesn't mean our electric bill savings also need to end. With more than 4 billion screw-based light bulb sockets in the United States, getting an efficient bulb into each socket also is really important for our environment because the energy savings would be massive."
The NRDC's goal is inspire more people to buy compact fluorescent lamp (CFL) or light-emitting diode (LED) lights. The agency estimates that consumers would save $13 billion on their electric bills if a CFL or LED is screwed into every socket. Altogether, the nation would annually avoid the equivalent of paying for the electricity of 30 large coal-burning power plants.
Light bulb packaging is required to help consumers make efficiency choices as a result of the six-year-old Energy Independence and Security Act, signed into law by then-President Bush. The law also required manufacturers to improve efficiency, even for standard incandescent bulbs that look the same as but operate more efficiently.
CFL and LED lights use 75 percent less energy and last 10 and 25 times longer, respectively, than incandescent bulbs, according to the NRDC.

More long-finned pilot whales were found stranded today on beaches in Tasmania, Australia. About 500 whales have become stranded, including at least 380 that have died, the AP reported. It is the largest mass stranding in Australia's recorded history.

By 2030, almost a third of all the energy consumed in the European Union must come from renewable sources, according to binding targets agreed in 2018. Sweden is helping lead the way.

Naturally Warm<p>54% of Sweden's power comes from renewables, and is helped by its geography. With plenty of moving water and 63% forest cover, it's no surprise the <a href="https://sweden.se/nature/energy-use-in-sweden/#" target="_blank">two largest renewable power sources</a> are hydropower and biomass. And that biomass is helping support a local energy boom.</p><p>Heating is a key use of energy in a cold country like Sweden. In recent decades, as fuel oil taxes have increased, the country's power companies have turned to renewables, like biomass, to fuel local 'district heating' plants.</p><p>In Sweden these trace their <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank">origins back to 1948</a>, when a power station's excess heat was first used to heat nearby buildings: steam is <a href="https://www.sciencedirect.com/topics/engineering/district-heating-system" target="_blank">forced along a network of pipes</a> to wherever it's needed. Today, there are around 500 district heating systems across the country, from major cities to small villages, providing heat to homes and businesses.</p><p>District heating used to be fueled mainly from the <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140" target="_blank">by-products of power plants</a>, waste-to-energy plants and industrial processes. These days, however, Sweden is bringing more renewable sources into the mix. And as a result of competition, this localized form of power is now the country's<a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank" rel="noopener noreferrer"> home-heating market leader.</a></p>
Sweden is using smart grids to turn buildings into energy producers. Huang et al/Elsevier
Energy ‘Prosumers’<p>But Sweden doesn't stop at village-level heating solutions. Its new breed of energy-generation takes hyper-local to the next level.</p><p>One example is in the city of Ludivika where 1970s flats <a href="https://www.buildup.eu/sites/default/files/content/transforming-a-residential-building-cluster-into-electricity-prosumers-in-sweden.pdf" target="_blank">have recently been retrofitted with the latest smart energy technology</a>.</p><p>48 family apartments spread across 3 buildings have been given photovoltaic solar panels, thermal energy storage and heat pump systems. A micro energy grid connects it all, and helps charge electric cars overnight.</p><p>The result is a cluster of 'prosumer' buildings, producing rather than consuming enough power for 77% of residents' needs. With <a href="http://www.diva-portal.org/smash/get/diva2:1232060/FULLTEXT01.pdf" target="_blank" rel="noopener noreferrer">high levels of smart meter usage</a>, it's a model that looks set to spread across Sweden.</p>

Scaling Up<p>A recent development by E.ON in Hyllie, a district on the outskirts of Malmö, southern Sweden, <a href="https://www.eonenergy.com/blog/2019/February/sweden-smart-city" target="_blank">has scaled up the smart grid principle</a>. Energy generation comes from local wind, solar, biomass and waste sources.</p><p>Smart grids then balance the power, react to the weather, deploying extra power when it's colder or putting excess into battery storage when it's warm. The system is not only more efficient, but bills have fallen.</p><p>Smart energy developments like those in Hyllie, Ludivika, and renewable-driven district heating, offer a radical alternative to the centralized energy systems many countries rely on today.</p><p>The EU's leaders have a challenge: how to generate 32% of energy from renewables by 2030. Sweden offers a vision of how technology and local solutions can turn a goal into a reality.</p>
