thumb|241x241px|Solarpunk may take practical inspiration from Earthships, which are an example of [[sustainable architecture.]] Solarpunk is a literary, artistic, and social movement, closely related to the hopepunk movement, that envisions and works toward actualizing a sustainable future interconnected with nature and community. The "solar" represents solar energy as a renewable energy source and an optimistic vision of the future that rejects climate doomerism, while the "punk" refers to do it yourself and the countercultural, post-capitalist, and sometimes decolonial aspects of creating su

Ecomodernism is an environmental philosophy which argues that technological development can protect nature and improve human wellbeing through eco-economic decoupling, i.e., by separating economic growth from environmental impacts.

The International Energy Agency Bioenergy Task 42 defined biorefining as "the sustainable processing of biomass into a spectrum of bio-based products (food, feed, chemicals, materials) and bioenergy (biofuels, power and/or heat)". As refineries, biorefineries can provide multiple chemicals by fractioning an initial raw material (biomass) into multiple intermediates (carbohydrates, proteins, triglycerides) that can be further converted in

Eco-innovation is the development of products and processes that contribute to sustainable development, applying the commercial application of knowledge to elicit direct or indirect ecological improvements. This includes a range of related ideas, from environmentally friendly technological advances to socially acceptable innovative paths towards sustainability. The field of research that seeks to explain how, why, and at what rate new "ecological" ideas and technology spread is called eco-innovation diffusion. thumb|A seat made from waste containing cartons, foams, and PET bottles

Technogaianism (a portmanteau word combining "techno-" for technology and "gaian" for Gaia philosophy) is a bright green environmentalist stance of active support for the research, development and use of emerging and future technologies to help restore Earth's environment. Technogaianists argue that developing safe, clean, alternative technology should be an important goal of environmentalists and environmentalism.
