| Summary/Abstract |
World population is projected to reach 10.9 billion by 2100, yet nearly one-fifth of the world's current 7.2 billion live without access to electricity. Though universal energy access is desirable, a significant reduction in fossil fuel usage is required before mid-century if global warming is to be limited to <2 °C. Here we quantify the changes in the global energy mix necessary to address population and climate change under two energy-use scenarios, finding that renewable energy production (9% in 2014) must comprise 87–94% of global energy consumption by 2100. Our study suggests >50% renewable energy needs to occur by 2028 in a <2 °C warming scenario, but not until 2054 in an unconstrained energy use scenario. Given the required rate and magnitude of this transition to renewable energy, it is unlikely that the <2 °C goal can be met. Focus should be placed on expanding renewable energy as quickly as possible in order to limit warming to 2.5–3 °C.

| Summary/Abstract |
As the world's population moves from rural regions to urban centers, it is imperative to design policies and physical environments that can accommodate such a massive influx. In response, many countries have been building cities from scratch, clearing greenfield sites and building at an extremely rapid pace. Additionally, existing urban centers have been slow to respond, instigating suburban sprawl. A new conceptual framework is needed, one in which existing buildings and infrastructures can be seen as spaces for grafting and injecting additional density and public space. A marriage of the philosophies of Jane Jacobs and Robert Moses is required, recognizing important cultural centers and economies, while allowing new buildings, infrastructures and ecologies to be incorporated in harmonious coexistence. In order to create alternative urban-design strategies, it is beneficial to study Spain, whose history and architectural philosophy has promoted a healthy relationship between the urban-planning policies of the past, present and future.
