Energy IQ: Consuming Twice As Much Electricity: Can We Do It Sustainably?

消耗目前两倍的电力 - 我们能以可持续的方式做到吗?

Increasing population, improved access to electricity and growing electricity demand in buildings will continue to increase the world’s electricity consumption. 

Did You Know: The world will consume twice as much electricity by 2050 1.

No, you didn’t misread the previous sentence. This eye-opening stat, however, is nothing new to those who monitor trends in electricity consumption. The world’s electricity production has already doubled between 1990 and 2015. What should matter most to you, your kids and grandkids is not “when” or “if” we’ll double our electricity production by 2050, but “how” we can double it in a sustainable manner.

As the Population Increases, So Will Electricity Consumption

Increased diversity in sources of electricity generation and adoption of distributed generation are components of a sustainable solution. But before we take a closer look at distributed generation and electricity diversity any closer, let’s examine “why” the world is forecasted to consume twice as much electricity by 2050. 

Access to electricity is essential in fostering more prosperous lives. It impacts a broad range of topics and industries ranging from healthcare, education and poverty reduction 2. Several countries have recognized the need for access to electricity and made progress over the last few decades.  

Electricity Access  by 2050Despite this progress, there are still more than one billion people around the world that do not have access to electricity 3. This is roughly 13% of world’s population, which sits at approximately 8 billion people. Combine a portion of this population gaining access to electricity with the forecasted increase in world’s population by two billion people over the next three decades, and two to three billion more people will have access to electricity by 2050. That’s two to three billion people who will have more prosperous lives. 

Meanwhile, for the more than six billion of us that already have access to electricity today, our electricity consumption per capita will change in the years ahead. Increased electrification in buildings and industry, combined with road transportation will continue to expand the demand for electricity. For example, buildings will need more electricity for space cooling and appliances as the living standards continue to improve around the world 4. On the other hand, technological advancements focused on efficiencies will reduce some of our consumption per capita. For example, use of LED light bulbs in recent years have successfully reduced our electricity consumption. 

Enter Distributed Generation and Electricity Diversity

As the demand for electricity continues to go up, producing electricity in a sustainable manner becomes even more critical. 

There are several advances taking place to sustainably fulfill this increasing demand. Diversity in the sources of electricity and distributed generation are two of these advancements. 

Electricity DiversityAn increase in the number of renewables being used for electricity generation is the first aspect of increased diversity in sources of electricity. In 1990, 99% of world’s electricity was generated using just five fuels: Coal, Oil, Gas, Nuclear and Hydro. Today, you can add wind, solar and biofuels to that mix. 

Renewables offer a near zero carbon and NOx footprint, and they reduce the carbon footprint of the overall electricity generation mix. Most experts agree that renewable sources are the final and preferred destination of choice for a healthier planet, but before we can get there, we need a solution that will bridge the gap between today’s electricity generation mix and the electricity sources of the future. 

This is where natural gas is gaining more ground. Natural gas surpassed oil and nuclear in becoming the second most commonly used fuel in electricity generation. Similarly, in the United States, the Energy Information Administration expects new U.S. power plants to be mostly natural gas combined-cycle and solar PV 5. Natural gas also offers decreased carbon footprint and emits 40-50% less carbon dioxide (CO2) compared to coal when burned per unit of energy output or heat content 6. Moreover, in selected cases, gas fueled power generators could produce both electricity and heat, increasing the overall efficiency of fuel usage beyond electricity generation. 

The second advancement is the move from centralized generation to distributed generation. 

Historically, electricity has been generated through large centralized power plants, with the need for centralization being a direct result of the fuel type used in the generation of the electricity. Through these power plants, energy in coal is converted into electrical energy, and nuclear power is converted into electricity. That electricity is then delivered to customers through transformers, transmission lines and distribution lines. 

“In contrast to centralized generation, distributed generation introduces an interconnected ecosystem of smaller power generation systems at or close to the point of consumption,” said Satish Jayaram, General Manager of Distributed Generation, Cummins Inc. 

“This proximity to consumption allows distributed generation systems to reduce the cost, complexity and inefficiency associated with transmission and distribution. In terms of sustainability, distributed generation offers the benefit of reduced emissions through integration of renewable sources with existing energy assets.”

In our journey to produce enough electricity by 2050, both increased diversity in sources of electricity and adoption of distributed generation are components of a sustainable solution. The complete solution will also feature new technologies, policies and other changes, which we’ll cover here in a future article.

能源智商:三种情况,最大限度地提高热电联产应用的优势

三种情况,最大限度地提高热电联产应用的优势
三种情况,最大限度地提高热电联产应用的优势

温室、医院、工业制造商和商业建筑主是许多转向热电联产的行业之一,也被称为 "热电联产"。他们享有从改善财务业绩到减少环境足迹的各种好处。 热电联产应用的高效率将原燃料中的能量转化为有用的能源是这些优势的基础.

在某些情况下,热电联产应用的这些优势将进一步放大。让我们来讨论这些情况以及热电联产应用的相关示例。

No. 1:您的业务的某些方面运行24/7

最经济高效的热电联产系统在全输出24/7 中运行。

这并不意味着您的整个业务需要运行24/7。相反,您可以识别运行24/7 的业务的各个方面,并通过热电联产系统为这些方面提供动力。同时,您仍然可以拥有公用设施连接和现场锅炉。这些功能有助于为您的其他业务运营提供动力,并可管理电力或热能需求的潜在峰值。使用热电联产和公用事业的结合的另一个优势是维护活动。这种组合使您能够在热电联产系统上进行维护和服务,而不会中断您的业务的电力供应。

在这种情况下,医院是热电联产应用的好例子。控制温度、管理空气质量、保持医疗设备的运行以及许多其他活动都需要一整天的电力和热能。

No. 2:对热能的需求是一致的;这也是一年中几个月电力需求的同时

多年来,许多设施利用热电联产应用,日益普及
多年来,许多设施利用热电联产应用,日益普及

销售或储存多余的热能通常是不切实际的。余热通常被作为废热排放,从而降低热电联产应用的整体效率和财务效益。当热需求(蒸汽、热水或冷水)保持在一致水平时,热电联产系统的效率就会增加。这种情况与电力需求并没有太大的不同,因为多余的电力往往会被售回电力公用事业公司。

The longer the simultaneous need for electricity and thermal energy, the more advantageous a cogeneration application is. In fact, a good guidance is to consider cogeneration applications if your business has simultaneous needs for electricity and heating/cooling around half of the year or more 1. There are exceptions to this, and some applications are feasible even when the simultaneous need is 2,000 hours a year, about three months. 

在这种情况下,工业制造是热电联产应用的一个好例子。工业加工所需的热能在整个工厂的运行过程中趋于一致。此外,在这些设施中,全年通常需要同时使用热能和电力。

No. 3:与天然气成本相比,电力价格高

如果在现场发电比从公用事业公司购买电力更便宜,您的经济状况会更好。许多发电系统在现场使用天然气作为燃料,这就是火花蔓延的地方。

火花扩散是对天然气发电发电机的盈利能力进行评估的指标。这是电力价格与发电所需天然气成本之间的区别, 2 。随着火花扩散的增加,热电联产系统提供的节省也在增加。火花蔓延是财务可行性的指标,但并非衡量盈利能力的确切标准。

电力成本高且天然气为燃料的设施是热电联产应用的好例子。
